What it is, is that there is a certain amount of time that the seller/buyer can turn a transaction around or dispute it and the gambling/casino sites do not want to put up with people scamming them out of money.

I know people here, and myself wouldn't do that, but there are scammers who would so it's better to just not have to deal with that situation at all.

Plus there are fees and at a certain point the buyer/seller has to take care of those charges.

I've been a member of Paypal forever, for online shopping and ebaying so I'm not new to the program at all.

That is my opinion on the situation and I think it is a well thought opinion honestly.
