Starmap authors should be able to assign policies to their Starmap.
If a new Star post into the Starmap violates a policy, the author is warned about this before posting. If she continues posting nonetheless, a warning is displayed along the new Star in the Starmap for everyone to see.
Policies can be used to (soft-)enforce group guidelines and content restrictions, moderate discussion formats (e.g. every Star needs to be tagged #pro or #contra) and for various other things.
