I am getting high number of clicks - fake! What to do?

Don't worry more than 1% is normal but more than 10% is abnormal..

 

Go On your cpanel and check to see if you can identify who is clicking all those ads. Look for a repeating I.P Address that you find suspicious & I.P ban it.

 

CTR below 5% will never be a issue and Google won't ban you for it.

 

it could be an amazon.com spider. Happens all the time. Check your analytics and see. Try blocking amazon with your htaccess for a day or 2, if that don't stop it, and until you figure out the problem, disable the ads on the site using your allowed sites option in adsense. this way you can leave the ads but adwords customers are not charged and if google does a manual review they will see that you are doing something about it.

 

Report to Google is the best way. I have had the same problem with you. At that time, I reported to google.
