The biggest impact I have experienced so far has been that popups for cam sites, porn sites and other such affiliate marketting referal attempts lead to an age verification page rather than directly to all the "hot singles in my area looking for sex".

I don't like it, but for the most part the internet is now a better place for me to browse.

Do you not use an adblocker? I can't remember the last time I saw that kind of ad..
