Why I block (Score 1)

1. I block them because they are annoying. I never asked for the information so I don't want it invading my privacy unbidden.
2. I block them with whatever agency works best, usually a combination of privoxy and site-blocking in the router.
3. No, internet ads are just as annoying as TV ads. The difference being that internet ads can be blocked, while TV ads at best only can be avoided by changing the channel for a while - and yes, I do a LOT of channel-zapping.
4. No, I do not buy magazines and newspapers because they have so many ads. In fact I'd prefer to get them all in an easy 'throw-away-at-the-store' appendix if ever possible (preferrably bundled with the sports pages, where relevant). However, the various editors I've approached with the idea has so far been rather less enthusiastic about the idea.

Look, when I'm interested in a particular product, I Google for it. The various manufacturers thus gets my attention when I'm willing to give it to them rather than them annoying the hell out of me when I'm doing something else.
