I have been told by several different people that AdFoc.Us didn't payout, but nevertheless, I trusted it and started driving my traffic sources here, until I had made roughly $50 in earnings.
I requested that payment within minutes of the "Request Payout" button being able to be clicked on the Payments page, and now it is the deadline day and I am still yet to receive any payment.
I did also submit two support tickets a few weeks back with regards to other issues but I lost the ticket ID's (my fault), so if they did contact me back, I can't now find it. There should be a way to "recover" a ticket ID, or at least email me the ticket ID when I create it so I have access to it.
