The truth of the matter is, there is no way to avoid or win chargebacks with PayPal unless:
1) You are a larger business with dedicated account management
2) You have industry risk tools to help you analyze purchases
3) You have large negative/black lists that cater to your specific industry
4) You enact painful and impractical methods of control (such as snail-mail verification)
5) You have an auto-system set up for risk management and fraud prevention
Getting a copy of their photo-id is not enough.
Unless you are a solid business operation, with tons of transactional history, any sort of chargebacks will run you the risk of having your PayPal account suspended and your funds Frozen (few years back, there were two incidents of sellers who operated on PA who also did their own sales on the side. One shared member, who had been purchasing from them directly for about 3 months, did wholesale chargebacks totaling around $40k to both of them. They both had to shut down operations, but one guy had it far worse than the other, in that he held his funds in an unverified PayPal account (a new one) which results in a freeze where he could not recover the rest of his funds (he may have gotten them back by now, not sure).
You're best bet (sure, it's a shameless plug, but really, there isn't a better alternative) is to use PlayerAuctions as your payment processor. This is our 15th year in operation, transact in very large volumes which allow us to communicate directly with PayPal on CB's for immediate resolution, and our systems work in tandem with theirs (we have the tools to do this) to help mitigate and stop fraud before it occurs.
And on those rare instances when it does occur, we absorb it, you don't.
If anyone wants to guess what our CB rates are, and our fraud loss rates are... I'd be willing to entertain that discussion with hot/cold responses for fun
