Did some digging and reading in the official fs subred This is what i have found
""Using Patreon is not against our Terms of Service.
Preventing access to mods for our game via a paywall, directly of indirectly, is against the Terms of Service.
If a modder has a Patreon account but all the mods are freely available for anyone regardless? Great, sweet. Awesome. I personally McFricken endorse it. Modders already get a reward per download from us but we are totally not against them making some extra via Patreon, Ko-Fi or whathaveyou.
The problem we have is, if people hide a mod behind a paywall. Be it the finished mod, beta access, early access etc. We do not want that and stuff like that should be reported to "abuse ät giants-software.com"
Refusing to follow our ToS can and will lead to an exclusion from the official ModHub And Giants Products. And yes, we have done so already in the past with some modders who did not comply with our wishes. ""
So Sadly patron is still goes against their TOS :? ^ as stated they do not mind if you accept donations but placing mods/content behind a paywall still goes against the TOS and they have taken action against those who do not wish to follow their terms in the past... Hopefully this helps and i wish you the best!
