karthus scripter

Hey just went up against a scripter who was auto attacking minions perfectly for kills and using his q at the exact same moment to shit on my mid and jungler perfect calculation for his ults, e toggle for melee champs and ranged champs who went into his exact range. He never auto attacked any champs the whole match

Following this he had hairpin dodges on every skillshot launched against him with the exception of instant spells or if he was impeded.

I thought you guys had a system to deter script users? this is like the first guy i have seen though in 2 months that seems so blatant
