Where / how did people find the little Carrier MOV videos?

Hello!! New to reddit ( having an account) and wondering HOW or where people found the anarchy secret vids on the carrier channel, if theres any more, or in general just tid bits about them

also unrelated but oh my goooodddd the character having Steve skins is KILLING ME. i want to draw siren and NO_ONE but i dont know what they look like because theyre just steve... i feel like id get bombarded for making up ones w/ headcannons based off of those iconic "cool gamer" skins..
