Mastery Exploit Fixed: 622 Players Banned

Tamat, the Lead Community Manager had the following to say on the Mastery Exploit from a little while back:

Summoners, 

If you've been playing online games for any length of time, you probably know that most games eventually have to deal with scum of the earth cheaters that enjoy ruining your experience. League of Legends is one of the largest games on the planet, and the downside is that there are more people actively working to find exploits that create an unfair advantage for other players. 

That's bull****, and we're not going to allow it. 

We take this seriously. Nothing is more important to us than the sanctity of our game, competitive or otherwise. As soon as we discovered the issue, we immediately dropped everything to find both immediate and permanent fixes. I'm happy to report that the immediate fix has been implemented, and we'll be restarting all regions this evening to add some redundancy which will prevent similar exploits in the future. As we continue to investigate and further analyze data, our primary commitment is identifying players affected and doing everything within our power to make it right. 

Is this the end of people trying to ruin your experience? No. But we're committed to stopping this kind of behavior in its tracks, and are discussing ways to increase our monitoring and development as part of that commitment. We have comprehensive logs and data that allow us to see precisely who did what, and also who was negatively affected by this malicious behavior. We’ve identified all of the players that have been using this exploit, and we’re going to be taking firm action against their accounts. 

This kind of stuff is unacceptable, and will never be tolerated by Riot Games. For those of you who have been reporting the issue, thank you! We've been deleting all threads about it in the forums to keep visibility low, but we've definitely appreciated you making us aware. 

Update: We have comprehensive logs and data that allow us to see precisely who did what, and also who was negatively affected by this malicious behavior. We’ve identified all of the players that have been using this exploit, and we’re going to be taking firm action against their accounts. As we continue to investigate and further analyze data, our primary commitment is identifying players negatively affected and doing everything within our power to make it right.

They've taken down the number from the post, not sure why though.

  

Did someone mention a scumbag?
