Regardless of the outcome of this poll, it can't actually be banned - Fact. It can be enforced that gift is not requested in For Sale adds. But that's about it.. It's down to buyers to be vigilant and do what they feel is right. The real deal is carried out by PM's, phonecalls, emails etc. therefore that is when buyers and sellers will do as they please.
I can only suggest 2 things: -
1) Is that Col runs a bring and buy stall from his house?
2) Lobby PayPal to have the option removed for everyone.
I don't see either happening..
