glownigger 

A governmental agent (FBI, NSA, CIA, ATF) making bait posts on forums and image boards to entrap individuals or gather intelligence. The purported goal of glowniggers is baiting potential criminals or gather intelligence about a particular online community to reveal their intentions or beliefs.

The practice of posting as a glownigger is called glowposting.

The term was coined by paranoid-schizophrenic internet personality and Temple OS programmer Terry Davis in his livestream. "The CIA niggers glow in the dark, you can see them if you're driving. You just run them over " - Terry Davis, 2017.
The term was popularized around 2018-2019 on 4chan.org (specifically the /pol/ board) and 8chan.
