The seven-day trading restriction has caused discontent among many players. Especially those who liked to do skin trading wanted Valve to take back the changes. To bypass the lock,
OPSkins, one of the largest marketplaces for skin trading, has introduced a new feature that can bypass this trade barrier just a few days ago. The so-called “ExpressTrade” allowed users to trade their items without waiting and therefore faster than in the Steam Market.
However, Valve has now announced in a blog post that this feature violates their terms and conditions and that they will shut down all OPSkins Bots by June 21st. Furthermore, a Lawyer contacted OPSkins and told the company to cease using their intellectual property, such as gun models or pictures from the game.
