A note on my Fake AH Crew & Related, etc, nomination -- Fake AH Crew is incorrectly synned to a RPF fandom (Rooster Teeth/Achievement Hunter RPF). While the characters share names and (usually) appearances with the real-life letsplayers, the characters are actually the GTA V personas of the letsplayers, who, as members of an organized crime group, are roleplayed versions of the real people. About half the fandom treats this canon as "RPF in the GTA universe," while the other half (myself included) treats this canon as "fictional characters influenced by the rl letsplayers."

I'm happy to explain further if needed!
