flylink.io URL shortener is a SCAM website. The admin is cheating for years now. He change his rules all the time so the number of people who qualify to work with him are super small amount. BUT he keep all users and traffic, because he profit from all. He never paid tens of people, for which I know, not even mention that they are probably hundreds. I want to tell you all that the admin is experienced and know very well how to cheat. In the start he was paying, but then adsense banned his account and he scammed all after. The worse part is that he still try to use adsense, got many bananas from the shit ad network and yet he he try to use it. I DON'T UNDERSTAND that guy. I personally told him to stop use that shit ad network. Guess he profit enough while he scam people, so he doesn't care if shitsense will scam him or not.
DO NOT USE THIS SHORTENER!
