Much better, this is good policy to avoid some newbie scammer which launching new ico project and the main goal is to get fund from the investors and then run away took all the investments. By this i think only serious people who have real and good project will pay for this to make their threat much more interesting in the eyes of the people.
In the contrary, I would say it will enable more shady projects to get a good looking ANN and trick more people for the very small cost it has. It might reduce spam partially, but without any metric it will be hard to confirm.
