Spam, or pop-up/under ads?
Personally, I find pop-ups to be my number one cause of hatred towards advertizers. I don't mind (as much) hitting the 'delete' key and getting rid of one spam message, but I _do_ mind having to click 'X' when some uninvited window jumps up, offering an X-10 camera. And let's not even consider those on "adult" websites that spawn three new popups when you close the first. Ugh.
Further, consider the bandwidth costs of pop-ups in comaprison to spam. A plaintext email is just a few KB. A popup is likely to contain > 100 KB. I don't know the numbers on approximately how many of these windows are viewed (or how many spam emails are sent), but I would imagine that popups waste more bandwidth than email. At least, this has been my experience.
So I propose to ban all popup ads. It could be phrased in a way as to prevent loopholes (i.e., "The creation of a new browser window without the explicit request of the viewer."), as there are still some legitimate uses for the popup. I use Opera, which has popup blocking capability (and I keep it enabled), but it becomes a double-edged sword, as you can then no longer use a website that opens pictures in new windows when you click on a thumbnail. Ugh.
Some sites complain, when they start running popups, that it is the only way to survive these days -- that people just aren't paying for the regular banner ad anymore. It is not my intent to bankrupt these individuals, which is why such a bill would have to work on a national level (it would hurt more than help on a per-state basis). Granted, such a bill wouldn't have a chance of passing the current administration ("I say, that's Unamerican! yee-haw!"), but there's always 2004.
