There are a ton of patreons with nsfw content. But if this has been so for several months, than maybe some people seeing your games reported you for being an impostor, because they could not verify the patreon you link to from your profile.
Communication with devs could be better, but I also kinda understand why they tend not to tell people what is going on. Worst case they make it even more easy for scammers to upload their things. And best case, the dev does not even know about any investigation. And here it does not matter why there is any manual review. Be it to check eglibility for indexing or quarantine or whatever.
Two months is long but not unheard of and you also uploaded more games in that time, so maybe that put you at the back of the queue.
