Originally, the trading ban did not apply to traded items. Value changed this in March 2018 in order to take action against gambling, trading sites and scammers.
Gambling and trading sites were reliant on users being able to trade their skins quickly. Although the 7-day trading ban put obstacles in the way of the sites, many sites have worked out workarounds using virtual credits.

In the past, fraudsters would quickly trade the items across many accounts and ultimately sell them on an external site. The trading ban has made it much more difficult for fraudsters to do this, as Valve has more time to react.
