The part you quoted is speculation on my part, I wouldn't make a decision based on that.That's a great point and could be a possibility. I could have actually done it to myself :(. I'll definitely hold off on sending seller's name to moderators until I figure it out.
Do you not think they would have locked the second purchased account though as part of the investigation? That's where I'm confused if this were the case. I can still log into that account without issue.
Crap I hate to hear 6 months though....I'm trying to satisfy that itch by playing X4 Foundations but it's just not the same :(
Have you contacted the seller to try to find out if he wants his account back?
