Delete Your Account helps you delete accounts from online services
Deleting your account from a social networking site can be as hard as canceling a gym membership or convincing a telemarketer that you're not interested in their product. Social networking sites and other online services don't want you to delete your account. There's value for them in being able to quote huge and growing user numbers, regardless of whether those users are happy to be there (though of course they hope that they are).
If you're trying to cancel your Facebook, Digg, or LinkedIn account and you're having a tough time figuring out just how to do it, head on over to Delete Your Account. Delete Your Account is an online resource that helps you delete accounts from an ever-growing number of online services. It currently lists Amazon, AIM, Digg, eBay, Facebook, Flickr, FriendFeed, Google, Hotmail, iTunes, Last.fm, LinkedIn, Meebo, Monster, MySpace, PayPal, reddit, The PirateBay, Twitter, Wikipedia, WordPress, Yahoo, and YouTube, with others on the way.
When possible Delete Your Account gives you a quick link to the page that allows you to delete your account, and instructions on how to verify that it is gone. If there are any details that you need to know like whether a site actually holds onto deleted data, that's listed as well.
Happy account deleting!
