Sending as friends and family don't ensure you can't chargeback, just for your information. There is no assurance you will not do a chargeback. That is why people usually only receive PayPal from trusted members of the forum as it ensures not getting scammed. But, maybe there would be someone interest.
Mate, I'm new in this forum... But I think I have done more trades then you have ever done. Also with PayPal and big amounts.
So don't tell me about dealing with trusted members. Also It's not that really easy to chargeback in PayPal when you send as F&F... WHY SHOULD I CALL AND DEAL WITH PAYPAL FOR $7 THAT'S NOTHING IT'S A BIG WASTE OF TIME FOR THAT COUPLE OF BUCKS ALSO IT'S NOT 100% SURE I WILL GET THE MONEY BACK BECAUSE THEY WILL REVIEW THE CASE
You'll be surprised on how much scammers are willing to run away with. They even scam for a measly $1.
About your chargeback case claim, plenty of people got scammed with small transactions, because usually the bitcoin seller cannot prove anything in chargeback cases and paypal is always for the money sender. Especially when the word bitcoins are thrown around.
Edit: don't deal with that guy, he's run even for just $20 let alone $7.
