Post and pre game chat is monitored by the system.

You ban was actually for post game chat. It doesn't show up on the reform card (yet) which can be confusing, but we do look at it.

The reform card isn't indicative of the actual behavior. You were intentionally feeding as Nunu by running it down bot and then AFKed.
You have a history of this type of behavior as well as playing Kench, and throwing people into the enemy. I will be escalating this to a ban.
Here is your post game chat:
let me tell u a secret
u dont get banned for trolling
as long as u keep up in level and u dont feed
tickets dont work
The system does pick this stuff up. However, it isn't always easy for the system to decide what evidence to give in cases like this.
The trolling ends here.
