So, I'm generally a pretty big privacy advocate. If you don't want to share your personal information, that's fine. BugMeNot is a great site for those who don't want personal information collected about their browsing habits. Throw away e-mail addresses work well too.
What doesn't work is if you're applying for a position, and don't include any personal contact information besides your mailing address. Because we usually have a paucity of applicants, I made a bit of effort and was able to find the applicant's e-mail using their university's website. *sighs*
