Security Measures

Yahoo! has been implementing a lot of security measures lately. I have noticed a new security seal where you choose a picture to verify that the site you are using is legit, and yesterday, it offered a word verification before I sent an e-mail to attempt to stop spammers. They are really going to quite the lengths to make their users feel secure. (I have to admit that I find these measures slightly annoying as I just want to send e-mails, not have to go through a whole process to do so.)

What I think is ironic is that I also just noticed that in my e-mails, they highlight certain key words within the e-mail to offer helpful information such as maps or links. This makes me feel less secure, knowing that there is some way they are screening my e-mails for content. (I know Yahoo isn't the only system doing this, as Gmail puts ads on the sidebar that correspond to the content of your e-mails, but I'm very good at ignoring sidebars.) I just want them to leave me alone - just let me use my e-mail without any kind of special screening, ads or anything else. Is that too much to ask for?
