One of my friends asked me , why this happen : You have been banned for the following reason: cross forum signature link spammer He registered in two forums , why this forum banned him? Does that mean : you can't use the same signature in different forums?
Offcourse you can use same signature in lots of forums. There might be other reason for ban for sure.
I think the administrators of the forum are wrong. I believe that the signature is the right user, but the reply or thead should already be under the rules of the forum. It is my view.
Don't really get it, maybe they mean promoting another forum in their forum. In that case if I were a mod or owner I wouldn't want people promoting another forum in my own forum. That's like if you own a restaurant and people sitting in there are putting up advertisements to another restaurant when yours is packed to try to get a few to go to there own.
