I think that the Lobotomy stuff is still there just because it is so popular and the mods don't have an hold on it. As long as people use Castle, it's all good for the mods (They probably get money from it?). Idk what the age restriction level is, but I can play it from the profile (I'm 17)... I guess the younger people use this place as a startup for making games, so they don't usually put that much work into it, so it's rare to see actually good games...
I think someone falsely reported that deck. I mean, view it and see if it contains that type of crap. (knowing damn well there's some guy behind it, who knows)
