Also, I would recommend blocking users moreso than communities. Once you start looking for it, you realize that like 90% of these posts are made by just a few people/bots.

I wish there was an easy way to block everyone from an instance, like *@shittylemmyinstance.poop or something. Yeah, I do have one instance blocked to avoid the content, but the posters seem fine, but there are a few where blocking users one at a time is like whack-a-mole.
