It is pretty silly to ban people for having large avatars if they were bestowed upon them by moderators. Certainly some people were conscious of their over-sized avatars (in fact, some were a result of asking for them), but it really comes back to what the Admin does (or rather, doesn't) do or care about. Almost every moderator here doesn't give a shit (and if they do, it is usually once a month), and I think that's because the Admin doesn't give a shit, either. I don't blame the mods much at all.
But you should know by now that this is how CA.com works.
