Monster girls, furries, kemonomimi and just about any non-human but anthropomorphic thing doesn't get flagged as bestiality by patreon.
for the second part... if you are having a girl transform into a centaur by getting fucked by a horse... do you think it wouldn't be flagged as bestiality? that should answer your question.
From all my research. The above person is correct. I'll add to it.
To the OP,
If you want to make bestial like humanoids, you need to make them similar to the Bestial-Human-Anthromorph characters in the game Wild Life:
https://f95zone.to/threads/wild-life-patreon-build-24-02-2023-adeptus-steve.3810. If Patreon claims you violated their TOS, you can show a side by side comparison of Wild Life anthromorphs and your own anthromorphs, and they'll back down. Patreon fully supports Wild Life's approach. So do what Wild Life did, and you'll be fine. All my research supports this since I've had tons of correspondence with Patreon.
To clarify, READ THIS CAREFULLY: I've had Patreon email me back and tell me it's okay. Here are the criteria you should follow:
- Humanoid
- Bestial Like (Looks like a beast but also human like, with a bestial penis, this is fine)
- Can speak, showing that they're sentient and can consent.
Follow above criteria and you'll be fine. If there's any shadow of doubt, email Patreon support and they'll help you, they're friendly. The above is what Wild Life does, and they've been on Patreon for YEARS. To anyone who reads this, I'm strongly open to correction; assuming your citing Patreon correspondence via emails; NOT HEARSAY.
