I think pp stops it as they find them.A few months ago,there was a lady on ebay selling the lost vape Hacyon's at a great price,a member here had bought a few from her,then posted about the deal,so i bought one on a Wednesday night,and went to pay for it Thursday morning when i got paid,but Paypal would not let the payment go through.I contacted her,and she tried to get it straightened out with them for 2 weeks,but they told her as long as she was selling vape stuff,her account would remain locked.Look at all the vendors that sell ecig related items on eBay. I'd have to say 99% accept PP as their only payment option, yet they have no problems at all with PP... How does one explain that?
