I called him out on facebook a while back while he was trying to push parts. I made comments such as "has everyone received their parts that has sent you money?" and "Shouldn't you reimburse those due before you commit to selling to other folks?"
His response via message was this:
"Matthew, I am selling parts. When I was in a wreck and my son was hurt I was out of commission for a couple weeks. The motor that he "never received" sat in the shipping warehouse for two weeks waiting for him to pick it up. After it wasn't picked up, it was shipped back to me. He wanted a full refund, and I wanted to meet somewhere into he middle for the $300+ shipping I was out. A couple other guys packages were also delayed. To my knowledge every part was either delivered or money refunded. When the guy with the motor demanded full refund, I relented and told him I'd get it to him. Before I sent out the refund, he filed a complaint with PayPal, I didn't bother arguing it and they refunded the full amount. I haven't bothered much defending myself on dweb, partly because it's a lost cause and partly because I have been focusing more on my kid than slinging parts. This week is the first week for me back at it full time. I appreciate your question and civil manner as opposed to the name calling and b.s. on the forum."
