Sadly when we do report, things are routinely not removed. Mumsnet also use algorithms to identify potential violations independent of moderation reports, as per their submission to a government body a few years ago, and this doesn’t seem to be spurring any action against anti-semitism. I report every instance of anti-semitism I see, but even in the cases they do action a deletion - there is no willingness to go through and check the user’s other posts, even on the same thread.
I would really like to know what training Mumsnet moderators have on anti-semitism and what their application of the IHRA definition looks like, because the things they deem ‘political opinions’ in responses to reports fall under that definition explicitly. While I appreciate Mumsnet as a platform, I think it’s right to speak up at the moderation problems that have become clear with regards to anti-semitism. Otherwise, how will things ever get better?
