I know this isn't strictly computer-related, but I think it's a problem that many of us face, and so I thought this would be the better place to ask it.
I'm just wondering about how spam is eerily accurate when it comes to the subject matter of the spam emails. It seems like whenever I find something new to obsess about (be it a program or whatever), I seem to always get spam emails related to that very subject. For example, at one point I was very excited because I was getting the Adobe Creative Suite, and all of a sudden I started getting lots of spam emails advertising Adobe products. How did the spammers find this out? Lately, I've been doing a lot of college searching (I'm a senior in high school), and again, I've been getting spam emails pretending to be college invites. It's not a big deal, because I've never had a spam email fall into my inbox after switching to Gmail, but it's just kind of creepy because it seems like they know my every move.
How do they know what I'm up to? And I guess the more important question: How can I keep spammers from tracking me?
