I came across this today and thought it might be useful to other SurvivalBlog readers. It is called JustDelete.me. From the web site:
'Many companies use dark pattern techniques to make it difficult to find how to delete your account. JustDelete.me aims to be a directory of URLs to enable you to easily delete your account from web services."
Essentially it is a listing of links to various web companies where you can delete your account. Currently 129 companies are listed and the site owner has a method for submitting others for inclusion. - Clark H.
