Well not to be blunt, but many people are "pretty sure", but it's not what Patreon has told me...hence my mail to them to clarify EXACTLY what is and isn't allowed according to them, before taking any further actions (which might include just finding a whole different platform alltogether!).
Well your not the only one in this boat, so far seem some different developers.
a. Those who only change the public stuff on the patron site itselff, leaving out content censoring
b. those so scared they change content
c. those that were in b, but changed back cause patreons reaction to them they understood it doesn't matter
d. those who do not give a shit and went away from site.
Personally I agree sure, fine whatever their site their callupon from the USA giverment FDA i believe or something fine i take it.
HOWEVER, if you plan on sticking with the b route, cancel your game altogether. A step mom with her stepchild is still considered illegal in some states states of the USA. That means written out.
