Reported flags for this user for violating the rules.

He left an offer on my post. I accepted his offer. 10 days later he sends me a message telling me that he wants to back out of the trade. After I threaten to flag  him, he gets back on board to trading with me. So it's finally trading time, and after telling me some story about how the mob is on his defense team on Arena and not being able to retrieve the monster, he finally confeses that he has traded the mob away.
