Thats why I like the gift, because yes you will get away with reversing one gift, but anymore then that you will lose your credibility and paypal will have issues with you keep cancelling your gift payments.
Yeah too many gifts might cause a flag someday with paypal, so far I have not had an issue. Yeah I could see people having issues with ebay and hacked accounts I guess, but I have used ebay to verify the buyers and used the forums as well to have double verification. It helps avoid scams and only one person would get scammed as long as you post about the scam on the forum. I agree any virtual currency or anything really you have the risk of chargebacks with paypal, but no more then selling a computer on ebay and the buyer then saying someone hacked there account and they didnt receive the computer. Easier to help prove something was at least delivered though, which is why a paperclip helps with that as well, you can at least show that the sold item was paid for, the bitcoin were free. There is always a risk, but I do to also believe, we need to use paypal if we want to help bitcoins get more popular in the community.
You mean you found a buyer on eBay and asked them to get verified here? And they were ok with it? That's pretty smart. I assumed most buyers would not go along with that.
If you sent a tangible good, I think the buyer is responsible for mailing it back, but yes there are ways around that too.
I've been trying to educate BTC traders how to accept PayPal, but it's tough. Even I only limit my sales to 4 per week and that's by Mass Pay. haha You're only allowed to buy 1 BTC from me by credit card.
