Delete facebook account

There is a way to delete it permanently.
At the bottom of the homepage, there is a section called "Help," in this section go to "login / account settings" / "Other" / "How to delete my account."

If you can't find it, you can send an email to Facebook using this template:

I signed up for a Facebook profile, but I no longer wish to use Facebook.

Please delete my profile and all of its information.

Thanks

Then you need to wait a bit (a week or more) for them to delete your account.

the link to delete the account has changed.
help/ account settings/ privacy/ I want to delete my account permanently

then click on "this form"

and then all you have to do is check the box and send the message
