When I meant alternatives I didn't mean that they were payment processors themselves. Basically a bunch of companies in Eastern European countries that were neutral in the war popped up. The sites just accept MasterCard, visa, whatever and funnel the money to Russian artists. Not all were specifically for furry art but a few very much were.
Most are dead but boosty.to is probably the most well known and pretty much entirely targeting Russian furry artists. You also can see how much they actually make off their sales since it shows it semi publicly.
But this was the big list of them
