Yes, I know many have been paid.
But sadly, Adfoc.us is now officially a scam. You're reading this correctly, Adfoc.us is a scam.
This Christmas 2012, they added something to their website, this:
|Your account has a warning ("Red Flag")|
Why they flag your account red? Thousands of people have been flagged red, most of them is a regular earner who spends money on the program. They just flag you red so you can't withdraw, period.
Adfocus is a scam, what else remains now?
