I place targeted advertising in the "creepy spam" category. It's still spam.
If I was to receive an unwanted phone call from a travel agency while I am browsing plane tickets on the net, that would be creepy and annoying to me: I prefer to make thoughtful decisions by myself, thank you.
I realize not everyone thinks the same way. But in my opinion, advertisement has a severe net negative impact on our society, and would like to get rid of it altogether.
I already pay for targeted advertisement that comes in the news articles I read, no need to force-feed me.
I've seen that fun video (in French [1]) where a person asks various advertisers their opinion on the role of advertising in the society, then asks them about an "electric knife" ad that was then running. The cognitive dissonance that follows is hilarious.
