Once google disables your adsense account they will never re-enable it, they are really strict on this.
I never heard of something called inactive clicks before. Do you mean you don't get any clicks? Google doesn't kill accounts because they don't receive clicks normally.
I think that's not the problem, i have a site which is a month old, i haven't had a chance to update it yet so it only contains 2 posts but I already put adsense on it, I practically haven't done anything yet so there's no traffic which means no clicks on my adsense but it's still active. I'm a bit curious so I just went to google support, many people have the same problems, looks like google assume it as "invalid clicks" and according to the "victims" there's a better chance to win a lotto than to have them reactivate your account.. sounds ugly
