Shotly.io is a popular url shortener, that is always struggling to monetise its links well, and is monetising poorly, because the owner does not seem to be skilled with ad networks.
They have been changing the ad pages all the time, so 1 day there might be 1 popup and 6 banners, the next day there could be 4 banners and 5 popups, you never know with him. The ad pages are very unstable.
They use moneytizer, which pays 70-90 days after the end of the month, but the risk is on him, the owner, but you could still be careful!
