It's frustrating as fuck, I'm sure a lot of people have genuinely good intentions and just lack the knowledge to recognize what is valid criticism of the state of Israel and what is antisemitic garbage. The lines are increasingly blurred, which only serves to undermine criticism, endanger Jews, and promote Netanyahu's genocidal agenda.
Now, more than ever, it's important not to spread antisemitism, and to call it out, downvote, and report it when you see it. That shit never belonged anywhere in the past, and it sure as hell doesn't belong anywhere today.
