I keep hoping for someone to ask one of these ad-idiots how is "relevant" defined? Seems like it's buy something and then get hit with a zillion ads for the same damn product. Or is "relevant" have something to do with singing, dancing, blinking ads that take up half the screen or better?
Disclaimer: I do run a heavy HOSTS file and also Adblock. I've never clicked on an ad to buy something. I ignore the "ad" links in a Google search. Periodically, I drop the shields (except for 3rd party cookies just see if anything has changed. Nope. Same silly, irritating, bandwidth hogging shit.
And these ad clowns wonder why.....
