This is an update for anybody who listed a banner in their listings.
I made two banners on purpose. One said "Talk about this auction at AS" and the other said "Talk about crazy auctions at AS." One is a blatent advertisement, and one is not. The first one provides people with a related link to the auction. The other provides an advertisement, which eBay does not like. Sure they are both the same link, but it's the approach that eBay can call it on.
The second one is the one that caused trouble. Apparently even after saying "DO NOT USE THIS LINK IN AUCTIONS" people still did! :D
To fix this, I have uploaded a new one for BOTH images now. It says "As featured on AS."
I am sorting details on this still and will post here when I get more news.
