Faucet page can't be accessed if the user is not registered and logged in. Ref link is saved forever once the user registers through it.
Then, you not only take 50% from the faucet claims, but 5% from the amount they pay when they advertise.

By the way, just ~500 satoshis prices today, both for click and for 1000 impressions. We are definitely the cheapest place to advertise now!
