InfoDid the Overwatch system change?

Hello, Overwatch system seems to have changed. if you say how to know this i can tell. I only played a game in 21 hours yesterday and we're five premade and overwatch ban. Another person from the opposing team was cheated we reported it as a team and he said i'm playing two game in 21 hours and its my first game today after a while, he had the same overwatch ban so i think's Overwatch system is changed (11 report in 21hr gg xd)
//Sorry for my English.

no, nothing changed

Yes, something might've changed. According to various sources, including Gaben himself, (Reddit AMA), Valve has been working on detecting spinbotters and AA by using AI (ANI that checks for mouse movement before and after shots? They have of course not specified what it looks for so I'm just guessing). It is, supposedly, already in play and will automatically send someone it judges as a spinbotter into overwatch. The system is in it's early stages but it's something that, again, supposedly, is improving all the time. Right now all it does is send someone to overwatch because of it not being flawless, and it will probably always only be overwatch. Valve has also said that this is going to be one of the things they will spend alot of manhours on this year, because of it's positive results in catching cheaters.
