"benefits of personalized advertising"
What benefits? Let's see:
Telling me where I can buy more of something I've just bought? Nope.
Telling me about suppliers I have used? Nope.
Telling me about stuff I have already looked like and decided not to buy? Nope.
Telling me about stuff a bit like any of the above but not actually like any of them at all? Nope.
Telling me what other people bought after buying what I just looked at? Nope.
Telling me whats "Trending"? Nope
Telling me that People in (close geographical location) are going mad for (dumb item or product that is so shit it can't sell on its own merit)? Nope.
It goes on and on.
Personalised ads are an utter irrelevance. I repeat: an utter irrelevance.
Piss off and die.
Yours with extreme prejudice.
