AccountKiller (online privacy)
Want to erase an online account you don't use anymore? Concerned about your personal data online? AccountKiller gives you detailed instructions (including links to the offending sites) on how to delete your account for services such as Facebook, Google, Skype and Twitter. AccountKiller rates each site's ease of deletion using a color code -- white represents the easiest, gray indicates a harder process and black means deletion is near impossible.
