Why is Xerath not disabled?

I've seen info about this Xerath script, and I need to know... has it been fixed? If not, why isn't he disabled until they fix the problem? Three straight games, no one banned Xerath. Three straight games, opposing team picked him. Three straight games, I dodged because I'm not going to waste time trying to play against a cheat. Now I'm in low priority queue for no reason other than because I don't want to play against a game-breaking bug. So... he's not disabled why?

And an only peripherally related question. If I just don't play for however long it takes for Xerath to be disabled/fixed, will I still be stuck in low priority queue when I come back? Or does that bs clear after a couple days away from the game? Because being punished for refusing to play against bugs is an extra slap in the face, and having to do all the waiting to clear the low priority queue is stupid in this case. If I was dodging just because I don't like a champ, then fine. I'd deserve the wait times. But because of a bug related to a champion Riot hasn't disabled? Really?
