tl;dr: I think what it boils down to is, that there is no supereffective solution to this. I know, it sucks. What you can do is design your map in a way that it is palyable, if one player is doing nonsense. You will most likely only get rid of them by getting them bored with what they do or decide to stop on their own volition for some other reason. Threatening/ reporting/ banning them doesn't really work because they will just make another starter account. You should really read the first link i posted at least. That's what happens when your counter meassures backfire.
Meaning, how much of a deterrent is reporting in situations like this one: http://us.battle.net/forums/en/sc2/topic/20745724988
Blizzard obviously won't tell you when they address a report so I thought I'd ask if its worked for people before.
Not what you want to hear, but here is some food for thought (in case you didn't find these threads):

@somen00b: Go
I've sent 4 reports, which is double the number needed to silence someone, and no effect.
I posted this thread on battle.net trying to get blizzard to fix their lobby kick feature by adding a delay before someone can rejoin if kicked:

If you want that, please post so.
