I asked to be added as a mod of !communitytv@lemmy.world some time ago - I have a user on another instance who was the mod before, @pruwybn@discuss.tchncs.de, but due to cross-instance moderation bugs I couldn't do any actual moderation.
In getting this user assigned it looks like my other user was removed and a user with a slightly different name was added - @pruwyben@discuss.tchncs.de. I think I created this user when I was first signing up, but had some issue & now don't seem to have the login info, and it isn't tied to my email address.
I was able to re-add the correct user (mainly to get the Moderator View) but I can't find a way to remove @pruwyben@discuss.tchncs.de as a mod there. I only see the add/remove mod options when viewing a post by the user, so I don't know if there's a way to do it for a user with no posts.
Thanks!
Strangely, it seems to have been federated to other instances like yours and mine, but the post doesn't show up when viewed from piefed.social itself. I'm not sure why - I don't see anything in their modlog about it.
