Faceit Ban Revealer

Faceit Ban Revealer is a lightweight extension that allows you to find out in which match you played with or against a player who has been banned.

The concept is very simple :

When you receive a notification on the Faceit website informing you that a player has been banned, all you have to do is click on the notification, and you will be automatically redirected to the match where you reported him.

Admittedly, it's not very useful, but if, like me, you're very curious and want to know when justice has been served, it's quite enjoyable :-D
