[quote name='sp00ge']I've sold a few MK codes already on eBay without issue, in fact, one just sold last night. But I am listing mine as the code/card and will physically mail it. I do offer an email option to those with recent positive feedback, though.
My guess would be a competitor reported your listing and said the pic you used was theirs.[/QUOTE]
An old post I know, but this actually did happen with me once. I was selling a promo copy of Boardwalk Empire and noticed someone was using my exact picture, it was one I took with my phone and you could tell because I put it on my bed. I told them someone was using my picture, they didn't do anything about it. The auction ended. Lo and behold someone put another one up with my picture and I sent a stern email, they did something then and apologized.
Knock on wood, but I've sold dozens of DLC codes. They haven't done anything to me yet, I sold my Reptile code for 60 actually.
