Banned for "Hacked account?"

So I just saw my Sythe got banned because apparently it's not my own account??? I had this account for a very long time but had a period of inactivity too. I recovered my account via email reset link a few months ago and have been more active since. Only reason I can think I got banned is because yesterday I sold 1.8B gold and the buyer got insta banned and blamed me. So a salty buyer trying to anti-scam me or some shit.

Ask for any details you want for me to prove it's my own account and I can provide. Thanks.

 

Hello, reposting since my last post was rushed/didn't include relevant information.

Current email linked to Sythe : [redacted]
Virus scan:
There's no changes in IP or login activity from since when I recovered my account a few months ago, I had been inactive for a long period of time and returned around then. I haven't been hacked. I trade daily without any issues.
