Keys.txt

keys.txt was a hidden screamer on the Russian forum Games.gen in 2014, However, there is a safe version of this screamer that actually provides free game keys before it was inaccessible.

This screamer has a hidden page made up of "game keys". These keys are only for Counter-Strike: Global Offensive and Skyrim. However, if you click on any of the .txt files, result in a flashing image of Jeff the Killer, the same animated file what Anne.jpg uses. However, the website is still active to this day.
