I treat this place just like real life. The feed is not tailored to me, so I block lots of stuff. Rude people, people that down vote, narcissists, communities with bad vibes, if I interact with moderators after interacting in good faith, or if I post something I know to be factually correct but get some negative cascade in response I simply block the whole community or individual. I've blocked 200+ users and at least as many communities. I only care about real people that have the decency to interact cordially.
