Paypal has had this weird thing where it costs the seller money, usually about $20, if the consumer/tipper charges back; In the streaming community trolls use this to cost the streamers money because paypal hasn't caught up to the streaming industry....However they are starting to understand this and more streamers are winning their cases when they dispute the chargebacks. Like I said in a different post though, it's really digusting to issue a chargeback instead of contacting the seller/tipee and requesting a refund first.
