Is there a limit on how long a user can be suspended for? I ask because I came across this profile which indicates the user is banned until 2046.

@MichaelAlbanese There is a user banned until 2192.

What could they have possibly done?

I don't know (because I'm not a moderator).

On Mathematics Meta: Is this user suspended until 2092?

@MartinSleziak Oops so I missed by a century.

Questions about long suspensions came up from time to time, here are two on Meta Stack Exchange: Why not perma-ban instead of suspend an account for 275 years? and How long can a temporary suspension be?.

@user21820 So that user might come back sooner than expected. :-)

@MartinSleziak No, I missed in the other direction! See a comment on that meta post you linked to.

Oh, I see! Considering that I have posted that comment, you should have remembered it.

@MartinSleziak Factors of 2 are easy to forget. =)

@quid: Hmm, I think I should discuss something confidential with one of you moderators, that just cropped up. Thanks!

@user21820 alright.
