Probably because if PP finds out a seller is abusing personal in this way, they will get shut down.
That's exactly how I understood it.
But, if it's permitted behavior, how do you abuse it? What does "frequently" even mean? When does abuse begin?
Why can't they just state a clear policy, and interpret it consistently? Surely there is someone who works at PayPal who can figure out how to do that...
I don't find unclear. Don't use it if you* are a merchant. If you are in doubt as to whether you sell enough to be a merchant ask PayPal.
If you are a collector making the occasional sale to fellow collectors -- then you decide based upon how much protection you want from PayPal.
It just calls for judgment --- and if I can be grumpy here -- Heaven knows there's enough of that on the Internet.
