There is a popular Russian-speaking twitch/youtube streamer nicknamed "uebermarginal" (his real name is Anatoliy Artamonov) who is resident in the US with the US citizenship. He streams about politics, philosophy and other issues consisting of "intellectual content". He has strongly influenced the russian youth, especially those who are interested in academia and science.

On March 7, he had held a meeting with his paid subscribers. The entry price ranged from $30 to $500 in the Russian currency. Around half a hundred of people had attended the party. He then presented an offensive anti-semitic performance out there. One of the paid actors was instructed to play a role of "poor rabbi Silberman" (a meme in his online community). The "rabbi" was almost fully naked during the whole meeting, having only pants and a fake kippah on. He was told to act in accordance with many anti-semitic strereotypes such as greed, humiliating phrases addressed to "goyim", voicing out a number of Yiddish phrases. He was also forced to lick a drink up from the floor.

This was not the first time when he made an antisemitic joke. For example, there are some of ones on his main streaming web-page (I will give a screenshot down below). Forcing paid actors into licking drinks off the floor at a public event points out that his humor is merely sociopathic in its nature. Hence, his actions (especially this performance) have reached the point over the line and have come to be a exemplification of anti semitism.

Regardless of his intentions he, I think, teaches his auditory that this type of humor is acceptable and fun. Our small community does not have any resources and means to affect his behavior as he lives in the US. We truly believe someone in the US could apply some measures to have an impact on uebermarginal and hold him accountable for his antisemitic actions.
I'm putting the media files to prove my words:
