Delete yourself from the internet by pressing this button

When logging into the website with a Google account it scans for apps and services you’ve created an account for, and creates a list of them with easy delete links.
Every account it finds gets paired with an easy delete link pointing to the unsubscribe page for that service. Within in a few clicks you’re freed from it, and depending on how long you need to work through the entire list, you can be account-less within the hour.
So, to sum it up, it will only find those accounts you signed up with using your Google email address. Furthermore, it gives all this information to a basically unknown third party. Considering that's it's quite a habit to sign up using throw-away addresss, or special email accounts which will receive all the follow-up spams, this service is, mildly put, quite pointless.
