Now it got cleared.There were a lot of posts on the forum by a user called "bomb".
They said something like this:
THIS FORUM IS MARKED FOR DETONATION
THE FORUM WILL DETONATE IN X DAYS
THE BOMB IS ARMED
And then a guy called Prof. toriaty(or sth like this) came and said that he kidnapped gman and the mods couldn`t ban him...The story is longer but I think I said enough :P
Also, they couldn`t ban or infract "bomb" either.
