That makes no sense, except from an overstepping-legally-and-relying-on-unsophisticated-second-party point of view. How is a forum in any way bound to the game's EULA? As a trivial point, let's say the forum is owned by a company. So EA is going to sue the company for breaking terms in the EULA of its game? How did the company become beholden to those terms in the first place?
