Keywords are:  'clan booting'

Clan elders can use the 'boot' command to boot unwanted trespassers from
clan areas.  If someone not in your clan finds their way into your clan
area and you want them to leave, you can use the 'boot' command to force
them to recall.

You must be a clan elder to use this command.  It will work on hidden
players and most gods, but it will not work on other clan members.
