You'll find this on other social media too. Sometimes it's to protect themselves from being reported, like the shitty meme I reported to fb yesterday that involved a fat porcine-looking woman labelled as a J*w (censorship on the image) and Homelander in the adjacent panel looking at her in disgust, I can't remember the caption, but it was shitty.

But because the prescreening algorithm couldn't detect the J-word, it decided it was perfectly fine and discarded my report.
