Hey guys, I was just thinking how ad networks run legally? For example, lets say I make $5,000 a month with "xy" ad network, how do they pay me? I mean most of the networks don't require me to send back any invoices. How do they certify their expenses to their publishers? As far as I know, if I would be an owner of an ad network, and I would not require invoices sent back to me from my publishers, I would have to pay the taxes on all the ad revenues, and then pay out my publishers = that would kill my profit. Please someone lighten me up! I'm kinda stupid in stuff like this. Thanks!
