Experimenting with blocklists is fine and how you find your comfort zone on Lemmy.
I once made an experiment in which I blocked lemmy.world - not out of spite, but to just see what the rest of Lemmy has to offer. Turns out, quite much!
Still, too many niche communities are hosted on .world, so here I am again.
Came here to say that!
I can’t comprehend why people would join instances in the list. If you don’t like a particular instance, just hop into the user settings and block it! Why let others set your blocklist?
