i guess i don't understand what you mean by "posting a link in the banned user's signature" cuz i just clicked on zuhair and there was no link to an explanation.
Like I said, one member has tried to return to the forums 14 times (actually 15 now, with an attempt to post pornography). We didn't bother posting the links for each one. If no link is present it means that either a) the user is a previously banned user or b) the user is a troll or spammer or other types who attack the forum with inappropriate (often obscene) material.
