Re: Fake Clicks
Google have a system called Invalid Clicks to try and filter out the clicks that might have been fraud, invalid and more. The system automatically refunds you if any type of click like this is identified, but depending on the case, this can take a few days. Now, one important thing to keep in mind is that Google can't stop those clicks in real-time bases.
You can learn more about invalid clicks here: https://support.google.com/adwords/answer/42995?hl=en

Hope this helps.
