Email I sent to Zuckerberg & Sheryl over "FORCE JOIN" Groups on Facebook

This company is trusted with 500 people’s data (and growing)?

Team Facebook,

Seems as if anyone can add anyone to a Facebook Group.

There is no “opt in.”

In this case someone added Mike Arrington and I to the “NABLA” group
on Facebook. I know I’m not a member of NAMBLA, and I’m going to guess
that Mike isn’t either.

I’ve now been assigned to a group that advocates… well…. ummm….
you can look it up–it’s very bad.

Also troubling:

1. I was never asked to join the NABLA group
2. I was never informed that I was “force-joined” to the NABLA group.

If you guys want to run these new features by me before you launch
them, I can probably save you from a couple of privacy law suits each
year. 🙂

best regards,


ps – Nice job on the .ZIP export.

  1. This would never be tolerated if it wasn’t FB. People would leave the site immediately. FB is the epitome of absolute power corrupting absolutely. It’s sad that people keep making excuses for them and are so locked into the “game” that they can’t leave..apparently no matter what happens.

  2. Alright guys, here it is. An application that will send you email digest from facebook groups. The app is called “Group Email Digest” and is available at or The app shows you a list of groups you are a member of (new groups as well as old groups) and allows you to subscribe to one or more of them for daily email digest. This will keep your mailbox clean and updated.
