I would not risk to accept Paypal from all users, the one sending the Paypal should be at least Full Member and maybe Member (with at least some trust), no lower.
now you claim that you're full member so you're trusted , possible this is purchased account
isn't problem when u buy via paypal
I didn't said I'm trusted because I'm a Full Member...I said that it's better to accept Paypal from some better ranked user that are here few months, than a newbie, new registered user and so on.Most likely a newbie will scam for even $1 here, which is a shame...With a higher ranked user you have at least a smaller change of chargeback, but it can still happen!
