AdHitz one of the most popular ad networks which allowed faucets traffic announced today that they will discontinue support for faucet websites.  This is the official announcement from their website:   

We have discontinued support for faucets.
We have found the quality, in general, is just too low.
Many real people feel they are obligated to click ads on the faucet page to keep earning even when not told to do so. This results in low-quality clicks that are in essence incentivised.
Also, there is a large percentage of faucet that suffer from extremely high bot activity resulting in the valid click rate being well below the minimum required.

Earnings will not be stripped and will be available to be paid out via the normal payout settings but we will no longer be supporting them going forward.

If you are the faucet owner probably the best option would be to remove all their ad codes from your faucets and replace them with some other ad network which still supports faucets traffic.
