Brief summary:
Aenu makes "fake bids" on everything. Literally everything. Not once a day, not twice a day, but multiple times a day. He's been doing it for years. (I actually have logs if required, but I'm sure you can look it up too.) If he wins, he will retract. He does this to drag others into a bid war (on behalf of someone else?) or to kill a FT topic. (I could discuss more about this.) I realise it's not directly against the rules, but he does it chronically. His actions counters the purpose of the forum. Go through his posts and transactions on a macro scale with AI to see how many topics he has killed off. I think this has been allowed to go on for so long because no d2jsp moderator is actually interested in legacy Diablo 2. (Understandable.) Most people will start a new topic with "Aenu posts will be reported!". Something has to be done!
When he is questioned about his actions he will play "boneheaded".
I'll tag him here so he can defend himself.
