What are we doing about inting Sion?

Basically the title. No regard for macro or team fighting. He just ults down lane, hit s tower, drops a zzrot, hits tower, dies, zombie hits tower, and then teleports back in to repeat. YouTube videos made of this strategy. What are we doing for abusing this? Kind of just sickening to win a game every other way, but still lose because there's someone that just doesn't want to play the game.
