I have a premium publisher account with adsense for more than 5 years so its extremely unlikely my account will get banned. Just every few months some guy from their compliance team sees the home page and assumes it is a paid-to-click website and disables ads for the website. Then I have to contact my rep to get it fixed. Ads are back up and running now.
But, aren't sites like Bitcoin faucets also against the ToS?
No faucets usually aren't, i see many of them using adsense nowadays. freebitco.in is classified as a game rather than a "paid-to" website.
