Earlier quoted context omitted.
Those ads were relevant though, and (I hope) not doing thousands of requests in the background; it was an IT-related ad, on an IT-related website, targeted at a person working in IT that was interested in new servers - what really is what the better ad providers are looking for. The rest is just idk, shotgunning and hoping something sticks.
I dislike relevant ads the most because they are most likely to influence my behaviour.
One example of advertising that I think is acceptable are the ads on the slatestarcodex.com sidebar, which are manually placed there by the author and targeted directly at the niche he writes in. If a computer could achieve the same precision when choosing what ads to run, and based its choices on the publication rather than the user, I think it would also be acceptable to me.
Would you find such ads equally unpalatable?
