Riot Games is already chalking the rollout of its kernel-level anti-cheat system Vanguard into League of Legends as a huge success, with the publisher proudly declaring its taken great strides to obliterating botting and cheating profiles.

Vanguard has put a “hefty dent” in botting in League queues, with bot play hours already slumping from more than a million a day to less than five thousand. Another 3.5 million slave bot accounts waiting to be sold were also pinged and shut down. “The idea there,” Riot’s head of anti-cheats Phillip Koskinas explained in the Aug. 22 blog on the topic, “is to lowly dehydrate the market for secondary accounts.”
