"Never attribute to malice what can be adequately explained by stupidity."
You will only need two Facebook links in your life:
If you are a Facebook member:
Delete my Facebook account [then follow the non-member link, please].
If you are not a Facebook member:
Get me off the Facebook database
Why do you need to do this? Because a friend of you might be nice but a moron. He reconciles his address book with Facebook, and then Facebook invites all non-members [you, for example] and nags them all the time.
