I was getting annoyed that EVERYTHING I looked up was getting tracked by FB. I followed this link: http://www.wired.com/2014/06/facebook-ad-tracking/,
which took me to this site: http://www.aboutads.info/choices/
I’d already had an ad blocker running on my computer, but the cookies this site found were… PROLIFIC! I can’t block all cookies, ’cause some of my sites NEED them (people I teach for and such), but now, about 1/2 hour later – my feed and my ad list is very, VERY different. So much cleaner! Nice!
