Question about the serverlist hack a few years ago?

I dont see any youtube videos talking about it from a few years ago and only a few topics on the steam discussion tab for gmod. The server lists were all changed from the usual DarkRP, TTT, Murder, etc to “AWESOMIUMSUX” and other like rude or disrespectful things about gmod and its servers. I keep remembering it as a fever dream and when i brought it up to some long time players of the game they say they dont remember a thing about it. Do we know what actually happened and if the people were caught?
