I saw a wave of the harassing spam they were getting right before they defederated. One was a meme about lynching drag performers. Another was a picture of an erection that was posted in what looked like every feminist and trans friendly space, asking if it was bigger than the ones owned by the denizens of the communities. I'm sure it was just a small fraction of what they were dealing with as more shitty little hatemongers find their way to Lemmy, but I happened to catch it by sorting by new at exactly the wrong time. I can't blame the Beehaw mods for not wanting to deal with the psychological toll that comes with manually moderating that kind of content.
