I like that these things are being revealed and I previously read stories that these techniques were getting less effective since more people are aware of them. That's at least half the battle. Legal punishment of this behavior is not something I think I would support since I would be worried about it being impossible or at least very hard to enforce properly.
Governments the last few decades seem to insist on the power to seize the electronic money of just about anyone. Not sure that's a happy development, but as the capability's there anyway, couldn't one just serve the advertiser an order to defend their false claim in court and take the fine out of their bank accounts if they don't show?
