Question to Riot (Lyte): Can you still get punished/banned on these new modes for griefing, etc?

Hi, Just played a game of Nemesis Draft and we got a Skarner who got really mad he got him, so he decided to feed like crazy and mocked us for it. Also provoked us to report him etc etc, he probably doesn't believe he will get punished in these kind of modes.

So my question is, can they get punished for it? If so, I really hope you punish this Skarner. He didn't seem to care about getting reports, so let's see if he comes and cries to you about why he got banned/punished and Lyte can smite him with an answer.

Thanks!
