Phillip KoskinasDirector of Anti-CheatRiot Games

Originally a cheat developer himself, Phillip Koskinas switched teams at the last second in an attempt to avoid sentencing, ultimately helping carve the very first League of Legends banwaves from the collective meat of the guilty.  Once he completed the punishment of writing 300 million ETLs, Phillip ascended to lead Riot Games’ Vanguard team, a PC anti-cheat product that causes VALORANT cheaters to experience a variety of emotions.  Shortly thereafter, he briefly served in Amazon Games' 32nd regime to delay an uprising of semi-autonomous smart toasters in Lost Ark, and Phillip now once again manages a portfolio of competitive integrity products for Riot Games, spanning all titles and platforms.
