Gregory's ServerIF YOU USE PAYPAL AS A CUSTOMER/CLIENT, especially for NSFW, you are not safe either. you can also be banned if paypal figures out what you're paying for with their platform
if you're sending payments via a paypal link or directly to a username, do not ever mention what it's for. especially nothing indicating it's NSFW
ask the artist you're paying to send an invoice instead. and don't talk about commissioning lewd shit on public accounts, and if you do, don't link/mention paypal
this is an example of one of my invoice templates on paypal. this is about as much detail as you should ever include on an invoice, and you can put less if you choose to, down to just the price total and nothing else
i'll add some specifics, like a character's name, if i feel it helps the client's comfort level or if there's multiple characters i'm charging for, to keep an itemized list of what's being paid for, but that's it
