Sorry... what do you mean by lock games? Do you mean like as in the same thing as in locking a forum topic (as in no one is able to post on that game's comment page anymore)?
Yeah, I have to agree with shayneii: You mean locking a game so that it can't be played but still viewed? I mean, it would make sense if the game were yours, but I doesn't make sense if another persons game were locked.
Or locking game comments, another idea from shayneii? That would only make sense if all posts were spam, but that isn't with any game.
Very true, very true. We do indeed lock them. And as far as games go(such as Flash games) they can be taken down by admins. If they needed to be. For some reason.
