Creators (5+ years of using Patreon) have had their Paypal terminated for selling adult content on Patreon: https://x.com/Miilkywayz/status/1960607816475140277?t=0KAD2ONGOqdf4RzgMjmucA&s=1...
It seems that using Paypal is the issue, rather than the platform.
EDIT: Patreon supports Paypal and Payoneer for content creators, but neither support adult content:
Payoneer allowed content explicitly bans adult video games:

Paypal also doesn't allow it. So essentially, using Patreon and accepting payments for adult content is currently against the TOS of both payment systems.
