I used it for one of my links in the past and never really benefited from it but if there is something that people would be attracted to than I see it as being profitable.
You should setup a facebook page with a link to it saying free microsoft points, or new CoD news or something like that, thats all teenagers look for these days, they'd just go clicking it like theres no tomorrow
Would be a lot more effective to just do one of the CPA lead gateways with that than adfly. With those you get payed something like $1 or so for each submitted form lol...
I don't use it, I hate seeing those stupid links littered everywhere. There are better ways to make money.
