I'm very sorry to hear about what you're going through, and I wish I could do more to help. Have you considered starting a Fanbox?

Fanbox is a Pixiv product. Both have been attacked by this same wave of censorship, somewhat earlier, and while there is still adult content there, the terms of what's allowable and what gets you banned have been getting tighter and tighter. I keep tabs on a number of creators over on ci-en, another similar site, and they've been getting crunched as well. DLsite had become so bad that some Japanese creators were dipping their toes in over at Itch. It's bad everywhere. The storm is raging everywhere.
Also, being a Japanese company, there would be complications with membership and funds transfer, the cut they take is sky high, put international transfer fees on top of that, etc. And I'd have to mosaic everything I posted, which...no.
