I'd block the single user instance of pleroma.ra1n.digital (would be best to block all of ra1n.digital) as they mostly just troll the fediblock hashtag and be racist, like... KKK racist.
Their alt is over at freedombits.org which is a "libertarian" instance we also have blocked because nazis are allowed to do stuff like the following.
Update, it's actually dav1d:

contacted mastodon.social staff as that's the major hub he's federating through:
