One of the reasons to is, so the instance seems to be lively and won’t close too soon. Because I don’t want another kbin situation. I don’t want want that blocks many instances or get blocked by many (besides the extremes off course).

there is a movement to unsubscribe from .ml communities and to block it from servers, because of the way the admins and their group behave, politically and otherwise. sometimes if an admin bans you from a community for your different opinion, they choose a not fitting rule in the ban message, and go on to ban you from all the other communities where they are a moderator. it is not rare.

when I registered I did not have a particular reason to choose this one, but I’m happy with it, would recommend. slrpnk is also nice. lemmy.world not so much despite the popularity. Otherwise I might try a piefed instance, for the merged crosspost comments and the ability to access Mastodon content
