Fix some inconsistencies in how this was handled, and clean up some unused stuff.
Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
Update #1:
Due to abusive users subverting our CI facilities to mine cryptocurrency, breaking out of the container sandbox in the process, we have been forced to take actions to limit the usage of the public runners to official projects only.
The policy will be enforced on 2023-03-23 (or before if we detect abuses).
Please see this issue for more context and to see if and how you are impacted.
