It happens very often with exchanger's sites who don't renew their subscripions. TG admins instead of unsticky threads and keep it in the same folder they move it to archive folder. Is this a way to blackmail them and force them to renew their ads??
Btw their advertising disclaimer its very funny! They wrote this warning to potencial advertisers : "You are NOT allowed to place ads to fraudulent sites, investment scams, or Ponzi Schemes." But you look to their banners, text links, sticky threads and 100% are ALL scam sites!!! :D
