Well to acquire a point you can use in voting would have to get one from a miner. That would be the same, no matter if you are a real person or an advertiser/spammer. Unless you gained points before with your own content. Even if the price would be 4x the amount of the cost of other votes, it can't be a deterrent because 4x a little amount is still a little amount. If a vote costs 1 cent then the spammer would pay 4cent. Not a big deal.
