As others have said, Swappa doesn't do anything, they refer you to PayPal. PayPal doesn't care either. I submitted evidence, including the buyer giving me positive feedback on Swappa, a video I took of the phone working properly with no defects and then being boxed for shipping, pictures from every angle, etc. At the end of the day, none of this mattered. The scammer loser filed a chargeback saying the phone didn't work and million other things wrong with it that were clearly negated by the videos I sent. He got all of his money back and he kept the phone, refusing to send it back. My only course of action was to file a small claims case and to travel to Florida for that, which wasn't worth the cost. No lawyer would take up the case since the value was around $750. I'm guessing it wasn't the first time this scammer son of a bitch did that. I wish I believed in karma. Never selling online again after that, even with a 100% positive feedback rating on eBay since 1999.
