It is possible to click the links multiple times per day or have a limit?

Ad.fly only counts 7 clicks from each ip address per day, so not a big time thing. If you can get multiple ip addresses, it's better.

I am from Canada - interested?

I have a Cdn for the original project, but I need one for this project: http://www.satoshihunter.ca/clicking.html It's the same thing - just click any 7 links, and you'll earn money. You can see your stats here daily: http://www.satoshihunter.ca/adfly.html
