Here’s a service that may be useful for a lot of people. Do you have those annoying services which you don’t use, from where you still get notification when someone’s followed you or liked you or something like that?
justdelete.me might just be the answer. Its a directory of popular services with links to deactivate or delete your account. You will still need your user ID and password for these services, but just getting to the link from where you can delete it, itself is half the job done.
