The creator of c/formula1, u/RightEnvironment created the community ~ 3 years ago I'd guess, posted nothing, never commented, and then disappeared.

Likely this user is not coming back.

I cannot remove this user from the moderator list. Can this be done for me?

I wish to do so to protect the channel from interference should the user become active again, or the account become compromised.

Of course, if the user comes back and wishes to rejoin the moderation team, I would welcome it.

Thank you for your time.
