Ubuntu to store copies of all users' address books

if i want to buy something, i'll go looking for it. until then, i DO NOT WANT TO HEAR ABOUT IT. EVEN IF IT'S EXACTLY THE KIND OF THING I MIGHT WANT.

ads have one of two different effects on me:

1. i ignore them, filter them out, just plain don't notice them.

2. if they get past my mental filter, it's invariably because they're excruciatingly annoying or offensive. that product and company gets blacklisted by me, instantly, until i forget the annoyance (usually permanent because i have a good memory).

the creepiness factor of targeted advertising definitely qualifies as offensive for these purposes. that results in not only the product/company being boycotted but also whoever they got my details from - e.g. if it was a company i've bought from in the past, i am instantly and permanently an ex-customer.

from my POV, all advertising is spam (because 1. it drowns out the signal and 2. it's unsolicited - i *never* ask for advertising) and i don't want any of it. email spam, phone spam, tv spam, door-knocking spam, political spam, religious spam, pamphlet and flyer spam, billboard and other street spam - it's all the same, it's all just spam.
