Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello, I tried logging in today and it says that my account is banned? Could I ask why this is? Thank you for reading this.
Petio - Horde Nostalrius PvP.

Thank you for replying.
Gold trafficking? Does that imply that I am a farmer and sell gold in my spare time? The most gold I have had at any point is around 160-170, insufficient enough to really sell anything in my opinion. My typical farming spot is in Dustwallow marsh and this amount of money can be easily obtainable by farming there for a week or so. As for 'suspicious' transactions.. The only thing I can really say that would be suspicious is that recently I got gold in my mailbox out of the blue at one point if that is what you might be referring to? Just considered it a free gift, really. I will trade it back to a GM if you want me to, I did not think it was against server policy to accept handouts, and if it means I lose my account then I will get rid of the gold no problem. Thank you for reading, Sir/Madam. I leave this reply for your perusal.

Excuse my ignorance here but who in their right mind would think someone randomly sent them Gold as a gift. Had you really received random gold it was likely a typo in the mail of someone sending to someone else and Instead of confirming you just kept it. Not against the rules by any means, but a total douche move. If that's what really happened

haha LOL

I shit you not, It's not the first time it's happened I once got a random 10,000G in retail, never met the person. do a good deed, good deed happens. Why wouldn't I take it? I went through my screenshots and I have more instances of when it has happened from players so.. No reason not to believe me really. Up to the GM to decide. (screenshots below, ones I could find of instances I think that they have mentioned idk)
