Bot Farm must be easily detect

I played with a Kalista Mid in coop vs IA, and she had TP smite, she fed as fuck and when i checked her profile, she had no masterie points and nothing, she is now lvl 30, and no restrictions, so i think u need to work at this point and ban the farm bot, it's obvious ^^ Thx to considerate my asking and sorry if it's a bad english level ^^ Ty Riot
