Scripter playing on an account since season 4 and not banned yet

I thought that riot already gives out bans for people using third-party programs like scripts? I have met at least 5 scripters in the past 5 days and they are all playing ad carry. The unnatural dodge movements and the auto targeting spells that can hit you even if you are in the fog of war is insane. Is there like a script sale going on right now? I just met an ezreal that would literally walk up under the turret (high gold low plat) and just dodge every single nami bubble and skill shot with minimum movement. His q and w would hit you even if you were hiding in the fog of war with no vision.
