I switched to firefox with noscript. Stop using chrome 90% of times. Turn off 3rd party cookie on default for all browsers. pointed doubleclick.net/com to 127.0.0.1 to /etc/hosts.
There are several work computers that are shared. The poor thing is trying to advertise to is but it is hopelessly confused. Between work and several staff of wildly different interests it can't target to save itself. It reminds
me of a comment on HN some time ago where it was mentioned that grocery store discount cards were randomly shuffled between friends to prevent tracking.
I don't run noscript, but I find it's just as helpful to hit ctrl-shift-P to open a private browsing window in Firefox whenever I'm about to visit a site I don't want to see future ads from.
I have a huge number of names in my hosts file. I use the MVPS hosts file but there are at least a few available along those lines. I also have facebook in it.
The web felt less creepy now.
