I don’t think it’s a good idea either, but it’s less egregious than filtering specific communities.

This filter is not part of any specific instance, it’s hardcoded into PieFed’s code. That means it applies to every PieFed instance unless the instance admin explicitly patches the code to remove it.

Got any other specific examples?

Each instance should be free to set their own rules. Individual instances blocking those communities is fine, but the PieFed devs hardcoding a blocklist that applies to all instances (especially one as opinionated and arbitrary as this) is absolutely not.

List of blocked words in community names:

shit
piss
fuck
cunt
cocksucker
motherfucker
tits
memes
piracy
196
greentext
usauthoritarianism
enoughmuskspam
political_weirdos
4chan

Seems like one of the PieFed devs has some opinions about the kind of content they dislike, and are unilaterally forcing that on every PieFed instance. I can somewhat understand filtering out curse words, but specific communities should not blocked by default, and definitely not hidden in a hardcoded list in the source code.
