Anyone here with an "in" with eBay?

I created an eBay account many years ago. I never did much with it, but I had it, it was there, and I think I used it to buy a few things.

Then a while ago I got an email saying I was permanently banned, without the possibility of review or appeal. I didn't think much about it, but more recently I've thought: Why?

What did I do? Why was my account permanently banned without any recourse?

So I've just had a "conversation" via online chat, firstly with a 'bot, subsequently apparently with a person, and they just said:

Nope. Permanently banned.

Now, I get that providing details to potential bad actors is a risk surface, so they simply don't provide reasons. I get that. But for me on the receiving end of this, si there anything I can do to get the case reviewed and the ban overturned?

Can I have my account reinstated?

Can anyone here help me?
