There is an issue with your user account

Has anyone else had this happen?

All had been going well until I replied to a discussion earlier and had a notification appear on my screen stating it was under review. It happened again when I then replied to another discussion. There was no action I needed to take, so I wasn't unduly concerned until the following appeared on my screen (see image below).

It's just as well that I decided to delay e-mailing the community manager to request this (my temporary account) be deleted.

I am completely baffled as to what the issue could be.
