People accepts Paypal from trusted users. They do take Paypal, but if it's from a new member here, they prefer PlayerAuction as they cannot be chargedback. The downside is the new user would be paying a bit more buying from Playerauction because of their fees.
People uses stolen Paypal and/or they chargeback. It's highly unlikely to happen if you're trading with someone that won't put his reputation on the line if he were to chargeback. While you, still new and haven't spent much time on Sythe, have nothing really to lose if you chargeback and get banned. I'm not saying you would, and I'm not saying you wouldn't.
