Yeah personally I think there are a couple different ways that portion of it could be handled. Let's pretend a company like Steemit INC utilized some system like that and did a 50/50 revenue split on those kinds of ads. They could take 50% of it and buy STEEM and do distributions in STEEM Power to accounts that qualify under certain criteria utilizing some sort of engagement metrics....etc. That way it would create buy support for STEEM. Or just not have to dump as much of it which would have the same effect on the market. Then if everyone is getting SP distributions the money would be vested to begin with.

Yeah I don't think there would be any issue with US regulations if part of the money was used to buy STEEM and then distributed to users but then again it also could get interpreted as paying users commissions....etc and then suddenly the same laws could apply where if the person goes over like $500 they would possibly have to issue 1099's like affiliate commission sites or adsense does. That is a headache for sure. It seems to make it a lot less of a headache if there is a way to distribute out of the reward pool or give people more of an influence over the reward pool with delegations.

That could be one way around it. Have the "Ad fund account" and when people meet certain criteria they could get delegations which will give them more power for a period of time. I don't like that idea as much but it could reduce a lot of headaches.
