I have to preface this with I have no complete list of services banned in the Russian Federation at the time of writing. Sorry if I recommend an alternative that is also banned.
Twitter/"X" had been steadily losing favor anyway. I'd recommend Mastodon instead. ( https://mastodon.social/about )
It's less popular than Twitter/"X"/"Xwitter", but reportedly it's very good for getting in touch with other artists. And... It's not run by a crazy-person. :)
Ko-Fi & commissions might serve as a way to generate income without Patreon - although it's not a replacement. Subscribestar.adult might work as a replacement, but I'm not sure how your audience would take that move. Since most people who have actual money to spend are adults, it might go better than you might expect.
Depending on how your community is structured, other voice over IP services might work out just fine. (People have successfully organized millions of 40 player raid parties in WoW long before Discord came along...)
