How is something like this even economical? All those servers to keep up with that request rate and all that bandwidth spent. Even as costs go down, I don't see how anyone can break even on this. The tiny fraction of a penny earned on this ad is surely outweighed by the cost to display it. And also the follow-on costs of increasing bounce rates and less time-on-site. Publishers have to be seeing less value in these kinds of ads that perform this way. It doesn't make any kind of economical sense!
