I've had the unfortunate experience of winning an auction from someone who muled the item to an account for me (we live in different time zones), and when I logged on to retrieve the item I received a message saying the account was "locked by TSWBot permanently." Assuming botting or some other 3rd party stuff was going on.
The user has transferred all of his 3.5k TG to a multi-acc, (zero posts, created account 10 hours ago, no description for why the TG was transferred), and hasn't yet responded to me. It wasn't a huge auction, 95TG iirc, it's more just sad to me that this is becoming a thing on Sigma. I left the D2jsp community for exactly this reason, and to avoid this kind of drama. I'll post the user's name tomorrow if I haven't heard from him regarding a refund for the item.
I think it's great that there's no section dedicated to scammers on this forum, because it happens so infrequently, but I do wonder what my next step is. Anyone got a suggestion on how to proceed?
