There are millions of people out there who just accept all this crap as normal. I just don't know how people can feel so comfortable about being constantly bought and sold online.
Ads in general skeeve me out. In the early days (2005-ish?), while visiting a video game forum I used to frequent, my computer was infected with malware delivered by a malicious ad. I didn't even interact with it—the page just loaded, acted erratically, and before I knew it, my system was completely locked down. My only recourse was a full wipe of that PC.
Since then, I've never trusted ads. And even now that some ads have gotten more "legitimate" (thanks to these five secrets advertisers don't want you to know!), they still seem sketchy just knowing how much money goes into them. Do banner ads on a website even result in more sales? I don't know, but obviously they must be conning someone out of their money because they pay so much out.
