I am not at all sure it would deter misleading ads, since the truth or falsehood of a given claim or set of claims does not necessarily matter much to a chunk of the population. I am pretty sure the mechanism the OP described might reward especially outrageous ads designed to break out of the cage and go viral, in the manner I described. I'm not saying it's not worth a try.
