Steam came up with a solution on how to pay their developers from Russia, Belarus and Ukraine: In the payout setting, they're requesting information about an intermediary bank, including its SWIFT code and country. I have attached an official Valve statement on this as a picture.
Maybe this can be a solution to keep your Russian and Belarusian creators after Payoneer stops working? As well as gather new ones?Because I know for a fact that there's a lot of people who seeking for a platform in this countries right now, and after Payoneer closer Patreon is unusable too. So I belive it could be beneficial to everyone. 
Thank you so much; using BMC was a great pleasure for me and my audience, and I really don't want to go...
