If it's like membership or something I don't think it's really a problem,most of the pins sold on sythe are from pinlines and that is stealing.I would talk to a mod for a second opinion.
Haha. Classy. If it's something that could be traced to the person then you'd have to assume you can't sell them here... If it's something that can't, why is it relevant at all whether or not it was stolen?
