When I first started I was scammed by Amazon Wishlist, people purchasing items, then cancelling said items, after their show (when expensive item was in payment for Skype show). So I only work onsite, and the only offsite payment I take, is Amazon gift card. I claim it immediately, i.e. pretty much the second I get the email saying I was sent one. So I add the balance to my account, and usually I spend it the same night, or within a few days. In 5 years I have done that about 15 times, and been fine, but mostly with the same 3 -4 people. I have never had an issue with it, but I prefer payment on site. The amount of people scamming out there, is insane!
Sites like Manyvids have 80% payout on tips, so I like to send folks who are wanting to pay offsite, that route. I think kinkbomb might have 90% payout on tips, but a lot of people have been having issues getting timely payouts, and timely responses from their support services, the last year. So, personally, I would not go that route.
I have had several guys give me a bunch of attitude for not accepting payouts like Rocketdog (I think it's called Rocket dog), and several other types of offsite payment. They will complain that other models have no issue with it, so I block them, and tell them to go hit those "other models" up then.
My experience has been that many of the people who don't want to use sites with paywalls and built in verification, plus IP blocking, are broke. Usually trying to get cheaper services, by playing up on the whole "well I just want you to get all the money, and not have the site take such a big cut", or they have issues, and have been banned by a bunch of sites for chargeback, and abusive messaging to studios and models etc. I rarely don't have continued boundary issues dealing with such people, so I mainly don't now, after learning the hard way.
