Never accept money through PayPal for services for adult-related stuff, it can get your account banned and the money can be taken, as they are not sex worker-friendly.
Of course, the platforms you work on won't know you are taking payments from PayPal or anywhere else, it's better to always stick with your platform if you can, as it's much safer for you.
Some people still risk it with PayPal, and some also use other things like CashApp, but I am unsure if they prohibit it like PayPal, so if you can, try and stick with the platform, it saves a lot of hassle around.
