There is if you wish to change instance, for example if your admins do something you don’t like. That’s a perfectly valid reason.

If you have to do it once or twice, sure. But that’s only an issue for a short time till your new account build up.

If you’re constantly having those issues, with multiple different admins of multiple different instances…

You might want to consider the common denominator.

You don’t have to downvote just because you disagree.

It’s not because I disagree, it’s because nothing you’re saying is contributing to a meaningful discussion
