I was just in a ranked game with a summoner named 'Dirtbag Copper'. This person played Riven in this game. From the start of the game she was able to somehow cause lag for everyone in the game. Players were locked up for minutes at a time. No one could do anything. First this bug needs to be found and fixed, secondly this player needs to be permabanned. That is all.

I was in this match. Got screenshots of the whole scenario. Will upload soon.

I got kicked out of the game and couldnt reconnect. Thought at first I had a dc. But once I was in the game I saw that there was an immense lag and not just for me. everyone was talkin about how they couldn't do anything.

The game was only moving in an intervall of around 1-2 seconds. Then everything held still, hence and repeat.

I was in the same ranked game. Riven's player name was actually Dirtbag Chopper. (thanks for posting Jesus) Yup pretty much same thing^ everyone froze and locked up, acting like a lag. A couple of us have replays we might upload to youtube if helpful, although i think it might not show anything because it was within the client. Please Riot, unfair ranked match for everyone. What a dirtbag.

EDIT: Also forgot to note that Riven had mentioned in Lobby to enemy team "Watch this. I'm going to make it lag" and that's what happened

Also, here is the replay for anyone that is curious. I will still try and youtube it.

Sorry for the mistaken name. Dirtbag Chopper is the correct summoner name.

This hacker needs to be perm-banned. I think I've seen similar reports of hackers that made the game lag already so maybe it'd be wise to take measurements to close these loop-holes that can be abused in ranked matches.

It's sad and unfair if victory in ranked gets achieved through such abuse.
I was really frustrated when I couldn't reconnect cause of this hacker. I thought that I couldn't reconnect to this game would get me perm-banned so I kept trying and trying but I just couldn't reconnect. I sat there crying until at some point I finally managed to barely get into the game again.
I am still very upset about this. And I was on the winning team in this match. I can imagine the frustration on the other side as well.

Please do something about this. Revert the match and get this hacker.

Seemed very much like a Distributed Denial of Service hack. Not sure how he made it happen, but certainly worth looking into Riot.

Bump for Riot's attention.
