Some people check the transactions manually and add the rewards manually. But it's also possible to fully automate it through PayPal's IPN (Instant Payment Notification) system. Basically when a successful payment is made PayPal sends a notification to a preset url on your webserver that contains all the information about the payment. If the player was logged into your site then you know which user to add the rewards to. Otherwise you can match on e-mail address or a name they put down in the comment box. The rewards are then added to the account through an SQL query or sent directly to the SA-MP server through the socket plugin.
However I would probably only ever consider using BitCoin again for payments because these payments are final and can't be charged back. It's just too easy for people to abuse the charge back functionality with PayPal. I'm not going to use names but I've known one person who got seriously in debt with PayPal due to chargeback fraud by a user (those in the know will probably get the two people I mean). Besides the fact that you lose the money you earned, each chargeback also incurs a $20 fee on your account that you'll have to pay out of your own pocket, regardless of what the original amount was. So that user made lots and lots of small payments and eventually charged back all of them on accounts of "unauthorized use". I think the total debt due to all the chargebacks was over a $1000. That's insane.
This is the worst case scenario, of course. But it can happen and it is the main reason why I'm not fond of PayPal anymore to receive payments.
