Why are usernames showing up as "Anonymous?"

Hi,

thanks for flagging this here, this indeed is a strange issue.

I've seen that there is a support ticket already - as this is a very specific technical problem, and I also cannot see from my position what went wrong, we will have to wait what my colleagues are able to find.

A user is not able to delete him-/herself, only the community team can do so. However I doubt that there was an actual deletion - In my personal view it looks like an issue in the database where the user ID is not correct any more - but this is really just speculation from my point of view.

About searching a username in the private message inbox: If a user is deleted, then the private messages of this user will also not be accessible any more. Again I don't expect that this is actually the case here, however it is not surprising me that due to this issue the private message does not show up. I would expect them to be visible again once this is fixed.

Thanks for the detailed response, @Julian! Yes, I submitted a ticket a few hours after posting this as I was becoming increasingly concerned. Thank you again for the response.
