I saw that a user was banned by moderator on my instance and their comments removed. I don't have a moderator, it's just me, I'm the only user. I thought I accidently fumble fingrred the ban button and restored their comments and appologize. Come to find out that they were banned from their own instance.

I'm not sure how I feel about that. On one hand it's good if it's a really bad user posting spam or worse. On the other hand it is a conduit for censorship. If an admin doesn't like what you post on another instance, then they can censor you everywhere. On top of that, it makes it look like I am banning people, and I don't like that at all if they're just making normal comments. It should say something else and I should get some kind of alert that lets me know so that I can decide if the comments on my instance are appropriate.
