Blocking hexbear and lemmy.ml no joke removes 95% of shitposting and socialism/communism spamming. Should be done by default. Just block any overly political sub tbh.
I'm not sure why you are getting down voted. I think it is a fair statement to say that a lot of that stuff comes from the far left part of Lemmy. The sad part is I have been seeing a lot of it now coming from Lemmy world
For all of those political evangelicals out there I could could care less about your political views. I just want to use Lemmy in peace.
I think every time a big leftist instance gets defederated, its users leave and move towards more mainstream instances. I remember lemmy.ml used to be somewhat neutral a year or so ago (I got banned there so here I am now on lemmy.world).
