I feel it's mostly politics, which I really was not looking forward to - getting away from the fever pitch, very angry American politics constantly flooding Reddit was a welcome break for like five whole minutes, there.

I try to block most obvious political shit, it just doesn't help because there's dozens and dozens of subs shovelling it out on the "front page".

I'd love to block lemmy.world but keep communities am subbed to (whitelist|unblock)ed . Not just i don't care much for memes , but there's lot of shitty peops on there (racists|reply guys|.*)

I would guess users who really want to participate, but having nothing to say. Memes are the easiest form of participation and everyone is unloading several years' worth from their folder like nobody's business.

Same with the proliferation of news articles, though those at least have a much higher likelihood of engagement. I'm not a very tech-literate person, so I'm really stuck scrolling by a lot of those.

The comments section can be depressing, and I sense I'm typically the only person responding to a lot of them at all. For a notably smaller userbase that should in theory carry more visibility, there's some neat stuff that inevitably dies in new.

You forgot porn. I'm blocking unwanted communities as I come across them. Slowly separating the wheat from the chaff.
