Did everyone go to the native model when ad-pocalypse hit e-mail and everyone started to use spam filters?

Current ad-blocks are similar to blacklists. They are very basic, but they do get the vast majority of unsolicited advertisement, so it works. I remember the days when some argued that you only needed to block chines IP ranges in order to stop spam.

Then the world started to use content filtering, looking for specific words or statistically pattern that provide a probability patter for spam vs ham. I would predict that a AP-style network that automatically submit articles into multiple "spammy" websites would automatically be flagged by anti-spam organizations and thus be quickly blocked.

Native ads is also currently in a bit of a problem with tax and customer protection laws. That might just be growing pains however.
