I believe any sane person without an axe to grind against this user would interpret that statement as...
If the user were to not send the BTC as promised after I sent the PayPal funds, I would have to lie and claim my account was hacked by someone and the PayPal transfer sent maliciously in order to have my funds returned. This could open me up to potentially having my PayPal account suspended and damaging my ability to conduct business. Therefore I did trust the user to a certain extent and gave them the ability to potentially harm my business.
That sounds like a stretch.
If PayPal is legitimately reversible, then there was no risk for iluvbitcoins in the transaction and the positive ratings should not have been posted. That was my original suggestion to iluvbitcoins - to remove those ratings.
If PayPal is not legitimately reversible (F&F) then iluvbitcoins appears to be saying that they would defraud PayPal in order to get their money back. Describing it as a risk is like saying that I risk robbing a bank if someone scams me on Bitcointalk.
In order to reverse an F&F transaction I'd need to claim unauthorized access!
Have you ever done this?
If I've sent an F&F transaction and I don't receive BTC, I've been scammed!
If you sent first - yes, but that has nothing to do with PayPal. Why would you defraud PayPal to get your money back?
