I recently created a bitcoin faucet website but i am facing a big problem with the shortlinks :
when i count the number of people that visited the shortlinks i found that it is bigger than the ones counted by the ad network because  some  of these visitors already visited the shortlink from other faucets.

the question is : is there any method that check if the visitor already visited the ad network before he access my faucet ? Huh Huh

How to deal with this loss?
