With this logic, everyone should be banned from Fiverr since all countries commit war crimes. This logic is stupid. Most Russians don't agree with what's going on, but they still have to live and make a living somehow. Fiverr's virtue signaling is hurting people, not helping the situation.
Some people, like myself, were working with artists who had completed part of projects and now can't finish our projects because we were submitting them in parts. I have two out of 8 art pages for my book and I am not going to start over with another artist just because my artist, who is very good and hates the war, is in Russia.
