It seems like it works like that:

Each advertiser has a deposit address where they deposit to their account.
Someone would manually pool funds from the different addresses to this address 1Pqd5pR2V53y59hhYyoRkusQrzC1W31V5g which is used solely for paying out publishers.
Since the admin hasn't been online for exactly a month it seems like there is no one to do this.

I'm taking off my ads now until he comes back, assuming he's not dead or something.
