Yes it's a popular place to upload hacks of multiplayer games. IIRC when I was doing stuff in more mainstream games like TF2, I remember seeing hacks that were released on other sites also released here. However there are dedicated hacks released only to this site. And some of the subforums here contain more information on their respected games than any other living sites. But when it comes to specific communities, I'd say the larger the game base is the less likely it is to have a dedicated hacker/group releasing their work solely on here when they could make money by doing it through their own hosts they control. In those cases this site works as a proxy for regular people looking up "CoD hax" and then find an abundance of tools/hax to use. Also there is at least some vetting measures that take place to ensure safety of any hacks/trades on the site. Which can't be said for a lot of other sites especially dedicated hack sites.
