Piefed has the option to use built in block lists for users and domains, along with a bunch of other stuff.

It all sounds great, but it's someone else making those choices for you.

Like, if someone said:

Evil people shouldn't be left alone with children

Like 99.99% of people will agree, everyone is onboard.

The issue is when a bunch of people then realize they disagree on who is "evil". Some people will only disagree on minute details, others will be complete opposites.

So a logical person, would likely prefer an instance without built-in filtering, because it's really not hard to do yourself.

That being said, some pifed instances don't use those features.

Like, I could make a list titled "Nazis to block" and fill it with 90% actual Nazis, and then the other 10% is people who taste soap when they eat cilantro...

The vast majority of people would want that blocklist. And they'd just "join" it or however it works, and my silent crusade against non-cilantro enjoyers progresses because now their outreach is blocked.

It's just a poor trade off compared to blocking the obvious problem accounts on sticking to well moderated communities. Especially since they that method, users won't see their comments even on other instances
