I recognized a few names on there as brain dead trolls or politically extreme zealots. I'm sure some are fine and maybe just got on the devs nerves for something petty or isolated, but either way you're right, let people manage their shit. Tired of people thinking they can nanny everyone else or tell others what to do or think or feel.
Edit:just to add, I also know one person on the list outside of Lemmy comments and they are a great person. They probably had one angry comment and the Dev took exception to that.
