Because @rra claimed that .social is unblockable due to its size, I'm going to try and mute that instance for the remainder of July. In fact, I'll do him one better and mute .art as well, just to see how my feed changes.
IIRC, "mute domain" actually means "block domain", so I'll be unfollowing a handful of people and also cutting off some followers... Nothing personal, consider this your "get out of jail free" card, no pressure to re-follow when my experiment is over.
Sorry to .social and .art followers, I'll be back on 1 August!
