How does this even work? I was banned for TWO WEEKS about 5 minutes after a game I just played. There can't be a riot employee looking at this so quickly- does it pickup on certain keywords? Or is it based on the number of people who report you? Any info would be appreciated, thanks.
It's the Instant Feedback System. Reports against you build up a case, and when it gets big enough the IFS will check your logs for the offending behavior. If the negative behavior is severe and/or consistent enough you'll be punished. The IFS does its review within 5 minutes of the triggering report(s).
