I don't object to advertising per se. There are many good reasons for advertising. Without advertising, how would I know what to purchase?<p>I have two gripes:<p>One is tracking. Most ads are served by a central server, Google AdSense for example. If I didn't block AdSense, then the AdSense server would know about all the websites I visit.<p>If all those exact same ads were served by the same servers that served the websites they appeared on, AND if my visits to those sites weren't reported back to Google, I'd be completely cool with it.<p>More recently my gripe is obtrusive ads. I'm cool with a banner on tops or bottom or on the side, but quite commonly I'll try to read an article, but then before I can do so I get a popup that either solicits a facebook like, or my email for their newsletter.<p>If I haven't even read the article yet, how can I know I like it? I might be cool to give you email, I might even enjoy your newsletter but to make a rational decision I need to read your article FIRST.<p>Finally, the last few years I have been experiencing brain seizures. It's not epilepsy but my own experience of them is somewhat like epilepsy. I don't really know but speculate that the world wide web is causing my seizures.<p>It is for the specific reason that I want to eliminate my seizures that I installed noscript recently.
