NEW THREAT! Expo-Guide. Mailing similar contracts from Mexico

IMPORTANT: If your company is Disputing demands from Construct Data (Fairguide)
On 13th February 2007 Construct Data Verlag signed a far reaching settlement with the Schutzverband gegen unlauteren Wettbewerb Before the Austrian courts. Following continuing widespread complaints about Construct Data's conduct a further agreement was reached on 21st Feb 2008, It now appears that Construct Data has agreed
  1. To cease the mailing of misleading contracts from Austria
  2. To cancel their demands for money against All companies who signed in error and dispute the contracts, regardless of location.
If you signed Construct Data's Contract in error you must now notify them in order to be covered by this agreement, (Please use the draft letter provided) once you have formally notified CD that should be the end of it, the nightmare is over! Analysis of the 2007 settlement (On the StopECG Blog)

What does the additional agreement of 21st Feb 2008 Mean?

At StopECG we are still not clear about the outcome of the latest agreement in Austria. Our interpretation is thus:
  1. Construct Data will cease mailing misleading Forms from Austria.
  2. Any persons who dispute the Contracts, regardless of the date of signing or their location can now cancel using the Letter of Cancellation
  3. Complaints received by Schutzverband will be forwarded to Construct Data and Contracts Annulled
  4. Construct Data may continue to demand money from persons who have made a payment, even if they disputed the contract and paid under duress, however experience tells us that when people make payments and then refuse further demands Construct Data does not go to court.
Your Status
If you signed in error and dispute CDs demands, do not pay, no ifs or buts DO NOT PAY CONSTRUCT DATA A PENNY. To be covered by the agreement you must notify CD that you signed in error. Please use the draft letter provided

If you have Previously Paid money To Construct Data But dispute their Contract Our Advice is to WITHOLD PAYMENT. You to should send the letter of cancellation; please be aware that there is a limited Chance that Construct Data may seek to impose a contract. StopECG would welcome such action as it would enable us (and others) to expose Construct Data's business tactics in open court. While we would welcome such action we cannot be held liable for your descision not to pay, if in doubt seek third party legal advice.

StopECG Comment
There have been a lot of false starts with Construct Data, undertakings that appear at first to be watertight have been systematically bypassed. Twice we have written open letters to Construct Data's CEO Wolfgang Valvoda 1, 2 These went unanswered and the unfounded demands against businesses all over the world continued.

For that reason we are cautious about the outcome of the new agreement. It appears that Construct Data are free to mail their forms from outside Austria, if their intent is deceit then we would expect to see them use forms that continue to mislead. There is also the issue of persons who have paid money To Construct Data, Many under considerable duress while being hounded by the debt Collectors, Premium Recovery AG

StopECG Calls on Construct Data to :
  1. Completely redesign their forms so there can be no doubt that they constitute and advertisement with a substantial cost associated.
  2. Monitor Future Communications, treating Any complaint that they are misleading as a serious concern and to modify forms so as to remove causes for complaint.
  3. Cease demands against All persons who dispute former and future Contracts on the basis that they are misled.
  4. Accept any form of words where the complainant is expressing that they signed in error as reason for cancellation.
Sent The Letter of cancellation and still receiving demands for money?

the advice is to WITHOLD PAYMENT and wait to see what Construct Data's next move is. Also please write ALL the letters of complaint suggested in the main body of the page below.
If you receive threats of legal action from Construct Data please forward them to and remember, STOPECG ESTIMATES THAT APPROX 80% OF CONSTRUCT DATA's 'CUSTOMERS' NEVER PAY, TO DATE WE HAVE NO EVIDENCE OF CD BRINGING A SUCCESSFUL COURT CASE AGAINST A COMPANY FOR NON-PAYMENT ON ONE OF THESE DISPUTED CONTRACTS They Can threaten and bully and bluster all they like, unless they go to court it is all worthless posturing.

If you have previously paid it appears you are not protected by the current undertaking made by Construct Data, this does imply a small risk of court action, however there are hundreds in your position. Please check this page regularly for updates and should you receive what you believe to be court papers, please email immediately

Company Info
Construct Data is perhaps the first company of its kind to target a niche market... You will only encounter The Fairguide if you exhibit in large trade fairs. They send a mailshot to exhibitors many of whom mistakenly consider it to be a communication from the fair organiser. People who have returned the form expecting a free listing are then hounded for money as the small print in fact 'commits' you to paying several hundred Euros per annum, the contract is self-perpetuating.

More Detailed Information on Construct Data AG can be found in the Research and background Section of this page

Contracts are mailed to exhibitors at major trade fairs, they often have the name of the event in a prominent position, this increases confusion. When Exhibitors contact fair organisers they often find that the organisers are unaware of the Fair Guide and it's activities.

Almost as soon as the ink had dried on their Feb 13th Undertaking Construct Data started mailing a different sort of form to the one which had caused them and their so called customers so much grief

See The latest Mailshot from Construct Data
Cover letter | Cover letter (Reverse) | Contract.

There is little doubt in out minds that these new forms are misleading in several aspects, for that reason we encourage fair organisers to reproduce the scans and to advise exhibitors to read the small print before signing.
it is hard to accept that such a confusing document could have been designed in error by a company already facing a serious legal challenge relating to the mailing of misleading contracts, in view of this, In April stopECG made a response to the new forms. Our generous offer was shunned and now our predictions are being bourne out with companies contacting us to complain that they have signed the new form in error and are receiving demands for money.

If you recieve a mailshot from Construct Data please contact the fair organisers. It is not in the interest of fair organisers to have external organisations targeting their exhibitors and most will take the time to warn their clients of the risks. Feel free to direct them to our specific

To Pay or not to pay

As a result of the Feb 13th 2007 and Feb 21st 2008 agreements detailed above stopECG has updated it's advice on this matter
  • ANY PERSON who signed Construct Data's Contract in error: notify CD of the fact. Once this is done do not pay, no ifs or buts DO NOT PAY CONSTRUCT DATA A PENNY
  • The Only group now outside the protection of the agreements are people who have already paid money to Construct Data. Their argument will almost certainly be that the act of paying constitutes acceptance of the contract. Please Consider The following.
    1. Following the court action against them and the 2 settlements Construct Data are in a very weak position under Austrian law.
    2. stopECG Want a court case where Construct Data attempt to enforce one of the disputed contracts, if one occurs and it is possible for us to present evidence against CD we will be there helping the plaintiff!
    3. Versions of the Construct Data's form have been ruled to be Deliberately deceptive. (Note 1, Below)
    4. As far as we can ascertain Just one company out of the tens of thousands who have refused to pay is facing litigation, The case appears mired and may have been abandoned. Court action has often been threatened both by the guide and the associated debt collection companies. In every other case we have followed the threats have passed without the promised court action occurring.
    5. Those who have paid often receive further demands for money, if you read the small print of the document you will discover that it runs for 3 years (or More if not cancelled), so paying another installment may not be the end of this issue.
Note 1 The ruling of The Chemnitz Regional Court made in June 2004 is perhaps the most damning we have seen against any guide, Furthermore The Austrian Advertising Council (ÖWR) has twice investigated the mailing and found it to be misleading, issuing it's most recent alert in January 2005 More...

Specific Advice for Fair Organisers

StopECG are strongly opposed to the marketing tactics utilized by Construct Data Verlag AG and feel that fair organisers have a duty to for forewarn their exhibitors. As a fair organiser you are in a unique position to save your customers from possible distress and expense.

We ask organisers to print a warning on their websites and also to include that warning in correspondence sent to all exhibitors. You should offer general advice that mail shots your customers receive may not be from your organisation, even if they use your name and refer to a specific event.

It will assist to process if you specifically mention that Construct Data may send forms to Exhibitors using the trading names Fair Guide or Fairguide.

Ask that your exhibitors read any form very carefully before signing it and ask them to contact you if they have any concerns

Sometime between May 2005 and 28th September 2005 the list of staff on and was removed and replaced with general email contacts, Remained on the company's servers, naming the staff in Accounts as well as EDP and the CEO. Wolfgang Valvoda Remained listed as CEO on a large number of the Link Farm Domains, such as - Present when Checked 2nd Oct 05, Removed when re-checked 30th Oct 2005

Some of the domains give the Email address for potential employess wishing to seek work. This address does not correspond to any of the staff listed above.

In January 2004 Construct Data registered a number of new domains, these appear to serve little other function than acting as a crude link-farm.

The Acquisition of domain names has continued ever since, most but not all of the domains below are part of the link farm. Initially many of the domains were hosted at IP address which also hosted link farms for Ovag International AG. At an undetermined date at the end of 2004 or early in 2005 Construct Data's domains were moved to the company's own IP block. Around this Time Ovag's Link Farm domains were also moved.

Unless noted below all now share the IP (Last Checked 25th Feb 2005). IP

Rulings Against Construct Data
Fair Guide's staff appear to have some difficulty in formulating a contract that does not lead to disputes with advertisers, negative publicity and adverse rulings. We hope that eventually the graphics department will make the adjustments necessary to stop the continuation of this farce....

The Chemnitz Regional Court ruled in June 2004 that the offers formulated by Construct Data AG are formulated in such a way that an intention to deceive in the sense of code 263 Par. 1 St GB German Criminal Code (Fraud) Please note that this is a translation of the original. A copy of the judgement can be obtained from AUMA Attorney at Law Silvia Bauermeister, email:, Telephone : +49 (0)30-24 000 103.
Fuller Translation:

The Austrian Advertising Council (ÖWR) Issued an alert in January 2005 that it has twice investigated the mailing and found it to be misleading, and hence in breach of the Austrian Advertising Code. The report goes on Construct Data Publishers Verlag were also asked to ensure that all future advertising should state payment obligations clearly and prominently and that its advertising should not mislead by ambiguity. However, the trader continues to distribute the mailing unchanged

This is significant in that it shows Construct Data are aware of the misleading nature of their forms this would make it almost impossible for them win a positive judgement in court
