I was checking my adsense reports today and I noticed a a massive CTR for today (206.25%) for one of my sites which normally has a CTR of about 1 to 2%, I have informed google that I beleive that the clicks are invalid but I am still paranoid about google banning my adsense account. I am woundering if there is anything more that I can do about this or is the ball now in google's court?
All you can do is now is wait. If the worst does happen, make sure you provide all proof that it hasn't been you. Sending an email to Google was a smart thing to do, just wait on it and hopefully they will let you know soon. Best of luck!
Here I am posting link where you can report Google about the invalid clicks: https://www.google.com/adsense/support/bin/request.py?contact=invalid_clicks_contact
