Honestly I don't know...
I agree those accounts accusing you are very bad since they're broke many rules (e.g. trust abuse, fake accusations etc) but... it's weird if it's just controlled by one person. If I'm not mistaken
there're 17 accounts gave you negative feedback, why someone really need to revenge when he's a scammer with 17 alts... it's true he really doesn't have any job, activity or tired? Even TOAA, CH, Laudanum, trolling accounts etc can be tired because I don't saw them around this forum again.
Not mean a user with
many negative untrusted feedback is bad, because I have many
negative untrusted feedback too (6 until now) but the different is those scammer didn't create sock pupped accounts in order to revenge me.
I know there're some accounts gave you positive reviews on your thread, but I just hope those your customer can learn trust feedback and leave it to you if the trade was done successfully without any issues (of course not a fake review).
You could be an innocent or you could be a professional scammer we just don't know...
This is just my opinion, I hope you don't take it personally.
