Google doesn't seem to be doing anything about the problem except closing accounts.
There's nothing they can do, there's nothing they will do, about regulating your traffic (I happen to believe there's nothing they should do)
Are you positive those IP numbers are actually clicking, or are they just visiting?
Yes, whenever you suspect there's some kind of a bot or other click attack, the best thing to do is take the ads off first. You could also put your own ad or image on the page, and see what your logs tell you from that.
