Is there anything we can do about antisemitism on here?

I was on a reality show site and one of the cast members is Jewish with an Israeli husband, and they started saying really antisemitic cra*, and banned me for saying “they shouldn’t have broken into Israel and started a war.” The antisemitism on Reddit is awful and it appears the moderators are antisemites also. Is there anything we can do? Not that I care about being banned, but they are spreading Jewish hate, and banning anyone who doesn’t agree. It’s a sad world we live in.
