How do they get that information? My family and friends don't really use it much (and to the best of my knowledge I've never been written about or been in any photographs that have been posted). I use things like Ghostery, noscript, ad block, etc. to keep tracking to a minimum. I don't search Google directly but only through duckduckgo. I'd be interested in hearing what other means they have of finding out information about me so I can block those as well if possible.
