Politics are one thing, but there are servers that without-a-doubt bad. Some for example literally have “lolicon” in the URL. Not doing that also may or may not invite trouble, depending on your local laws.
You dont’t have to deal a_troll_and_their_2_or_3_friends.lol, but there are lists of known-bad servers (#FediBlock brings up some results). Im talking about defederating those, that can almost universially be considered bad.
Just as a heads up, your post inspired me to get the block list updated. I imported the list from blahaj.zone (and will keep the two synchronised going forward). A lot of them were unlikely to federate here in the first place, but better safe than sorry, especially given that I’m already maintaining a defederation list elsewhere.
neat :)
