Discuss automatically cleaning up untitled and unpublished projects

[MichaelAkvo]

#4767 introduced a django command to clean up untitled and unpublished projects. Right now it's a one-off script, but we have the possibility to run it as a cronjob at a specific interval.

Possibilities

Make user aware

If we decide to go this route, it might be worth either making the user aware that these projects will be deleted on a schedule.

Confirmation dialog at project creation

Maybe asking the user if they're sure they want to create the project will also stop these projects from being created.
