So sad to hear that your Patreon page got removed. 😔 I hope that your luck will be better in the future and that it didn't set you back too much, but whatever happens, your fans will support you regardless!
Thinking about it though, couldn't you technically have both a Patreon page as well as a Subscribestar page at the same time? I can't seem to find anything in their terms of service that'd indicate any exclusivity clauses, and I've also seen a few other artists using both at the same time.
However, for your Patreon page, you'd probably only want to post content of unmistakably adult characters, so basically everything except borderline lolicon characters. On your Subscribestar page, you can just post all types of content.
It's not a perfect solution but at least it lets you use Patreon without any drawbacks, while still posting everything else to your Subscribestar. Also, did you get the option to appeal your removal, or are you able to reinstate your page at all?
