Rage Famous
The goal of people who search high and low for things that offend them, usually by taking snippets of information and presenting them without context. The object may be to damage someone's reputation or to eventually sue for damages, but it is mostly to ensure they are known as the person who "exposed" the offense.
Did you see how the parents took a screenshot of a lesson and made it look like the teacher was being offensive? Those folks just wanna get Rage Famous.
