Re: "its usual argument that people want highly tailored content"
My experience exactly. I just bought a label printer, I'm being emailed constantly with adverts to buy other brand label printers. How many label printers do they think I want? It's less "Targeted Advertising" than Mistargeted crap.
I've also never been on Facebook, but I get daily emails to my real full name, and private email address trying to get me to sign up. I know they got this information about me by slurping info from the Contacts of a friend who is on Facebook. What a cunt Company.
Remember the old joke "How do you know a Politician is lying?" "Their lips move"? I think that pretty much applies to Facebook and all their assurances too.
