That's cos you need to turn off tracking otherwise all your words and location and voice get recorded and tracked to build a profile of you to target ads at you. I haven't had any! I get enough of a gutsful DFS on the telly without seeing it everywhere I go online too! Its enough to drive you nuts. I seem to always get Justine quite pleasant ad, regardless of what I say/write, so stopping the tracking/following you around on the heroes seem to work.
