the term witch hunt and all that is just a way of speaking
Right, but you do understand that a "witch hunt" is based upon the witch trials of 17th century across Europe and US, particularly the Salem Witch Trials. The term means that there is no proof to the accusations and are actions which are harassing/harming someone/something purely out of selfish reasons or spite.
It has no bearing, even as just a way of speaking, about the ramifications resulting from supported breaches and/or abuses.
We don't know if SS will also apply these policies, you just have to look at the censorship that has occurred on pixiv lately.
That has, is, and always will be an issue for anyone who makes mature content. Look at Playboy in the mid-twentieth century. Penthouse is another. Hell, Larry Flynt had to go to the Supreme Court of the United States to get justice about a parody ad that dealt with adult content. That's on top of publishers, musicians, and filmmakers going to jail on criminal obscenity charges that we would now find hilarious.
All this is to say, it's cyclical and it's ever-present. Anyone who is in the business or is thinking about getting into the business should do so with that knowledge.
Patreon, as a business, wishes to remain a client of certain payment processors, who in turn have guidelines set that Patreon must follow. Those processors are following certain pressures placed upon them by regulatory agencies and statutes. Those agency and statutes are set by representatives of elected officials and the officials, themselves. Those elected officials are selected by the electorate during the voting process. If you are of age and have not lost your right/responsibility (depending upon your location) to vote, you now know how to affect change.
In the end, in order for Patreon to stay in business for those creators who wish to use it, they have to follow and enforce certain content guidelines. As such, that means creators do have to steer clear of what is currently considered more extreme by the average person.
Do I think developers deserve a second chance for those who can show they were honestly unaware they were breaching their agreement? You bet!
Do I have any sympathy for those who do not get a second chance? A little, and depends upon the developer. A few know they are in breach and are trying to pull a fast one. A few others are trying the old "I'm not touching you" argument that kids use when they are told to stop touching someone - they try to get as close to violation as possible but still being annoying and eventually, they will get into greater trouble because of it. Those I have no sympathy. For others, a bit more.
However - all developers need to know that "I didn't know" is not an excuse. They should, before even signing up as a creator on Patreon, review and know the guidelines inside and out. They should ask questions prior to starting their page. They always have the option to ask Patreon staff review their content before making it available, if they might be getting close to the line.
