Currently, fraudulent letters from the long-known subscription trap “International Fairs Directory,” based in Costa Rica, are circulating again. In these letters, trade fair exhibitors are asked to confirm the validity of their data, and the possibility of a paid advertisement with high advertising effectiveness is mentioned. If you receive such a letter, please ignore it. The sender is not affiliated with PSI and is not commissioned by PSI.
