Who told you that advertising is not allowed here ? You just have to higher rank for that, I would not like it to be banned in future as well.
As i said, this was meant to be in serious discussion, it was moved (also it seems obvious now you are here just for the campaigns)
How was he meant to know? The op post made little to no sense until you edited it five minutes after he commented. I wouldn't be against avatars being removed from display in Serious Discussion/Ivory Tower, but it's probably overkill to be honest. People generally aren't paid per post for their avatars like they are their signatures so it would be largely futile. Only Full Members and up can have them as well. Might be a different issue if any old newbie could have them.
