I've had a post from Mondoweiss, a progressive publication headed by Jewish people critical of Israel, pulled by a Lemmy mod. Not for a problem with any of the article's content, of course, but because mediabiasfactcheck put the publication in the same category as Stormfront.

QUESTIONABLE SOURCE

A questionable source exhibits one or more of the following: extreme bias, consistent promotion of propaganda/conspiracies, poor or no sourcing to credible information, a complete lack of transparency, and/or is fake news. Fake News is the deliberate attempt to publish hoaxes and/or disinformation for the purpose of profit or influence (Learn More). Sources listed in the Questionable Category may be very untrustworthy and should be fact-checked on a per-article basis. Please note sources on this list are not considered fake news unless specifically written in the reasoning section for that source. See all Questionable sources.

Overall, we rate Mondoweiss Left Biased and Questionable based on the promotion of antisemitic misinformation.

The ADL has attacked Mondoweiss in the past, and mediabiasfactcheck mentions the ADL in its justification for its classification. This is not just harmful to the credibility of the ADL, but destructive to a much wider infrastructure for protecting Jewish people.

Eva Borgwardt said it well:

We’re seeing a genuine rise in antisemitic attacks and white nationalist, white supremacist, antisemitic hate and violence. When white nationalism is on the rise, to cheapen the accusation of antisemitism by applying it to Palestinian rights advocates, including Jews, is incredibly irresponsible and dangerous.
