I Am A New Faucet Owner And I Recently Noticed That Some Claimer Who Came To Your Faucet After Claiming From Another Faucet And Already Visited It Shortlink That Happened To Be The Same As The Shortlink You Use In Your Faucet In This Case When He Visit Your Shortlink Another Time That Visit Won't Be Counted It Means You Loose Money 
Is There A Solution For This Problem?
Does Anyone Have Any Idea About That? ??
I think shortener will count it for you. They count unique view for each account or you can use browser.history.search function to check if they have click this link before. Is There A Solution For This Problem?
Does Anyone Have Any Idea About That? ??
allthough this is the widely known myth about it, in my recend test i asked a friend of mine (different ip, different country) to make an account on a shortener and give me their api details (we will call the shortener shortener x). so i took my friends api key and my own api key from shortener x and sent a few people to my friends api. as my friends api was second in my list they HAD to go through my api key first, therefore any of the visitors on my friend's api previously went through mine.
after about 1 1/2 hours of testing we saw the result of 1 succesfull visit counted. the average shortlink in that place counts 10 visits per hour, so while i cant say that it doesnt accept any visits, i can reliably say there is a definite difference.
tungag's browser.history.search idea could kinda help with this, but the biggest solution would be for faucet owners to make a third party service that reliable keeps track of this on as many different faucets as possible. as this would increase earnings for everyone.
