The immediate cause appears to be a filter in HF that scans Spaces, but HF is currently investigating the matter, including the possibility that it malfunctioned due to an error.
However, since we cannot rule out the possibility that there was an issue with my Spaces code, I am currently waiting to see the results of HF’s investigation.
Also, it seems there have been cases where people who were accidentally banned have been automatically unbanned without any specific notification, so I think it’s worth checking right now for banned people.
