In my opinion, it is never a good business decision to take payments for your business through a source where, from a legal standpoint, you don't have control because you are violating their terms of service.
It takes the control of your $ and puts it in the hands of not only paypal/google wallet etc. but also customers who can just make a simple statement and get all of your funds frozen and your account closed.
Just use the adult friendly services that allow you to run your business legally, and to keep everything that has to do with your business in your control. They take a higher %, but not only is part of that going towards your "store rent" for them hosting you on their platform, but they are paying out a higher % to the credit card companies in order to allow adult. Or you can always invest your money into running your own payment processor on your site and do all of your orders yourself.
