fizzle

It’s the first option on your list.

Not everything is worth keeping.

Admins can configure this on a per community basis.

I block posters and commenters I don’t want to see. Its that simple.

I used to avoid it because I thought I’d create an echochamber, but I’ve come to realise that there’s a few users with fixations about specific issues that just give me the shits honestly.

I agree that blocking these instances will dramatically improve your experience.
