A group of people that pose as would-be racists and hide out in dark alleys. When vulnerable women pass by, the "Troll Patrol" acts is if they are about to rape the girl and then at the last minute stop and yell, "Walk with a friend in a less dangerous neighborhood, or next time I will rape you!" as a means to scare girls into being safer. Troll patrols can also be used to teach lessons about other dangerous activities as well.

Bob was mistakenly arrested for attempted rape when performing his troll patrol duties. He's in jail now.
