I am looking for anything to back up this statement.

> Anything dealing with user deletion should go through a well established, legal approved process.

Which seems prohibitive. As though someone's personal emails/tweets/images on a free account are somehow protected from the whims of a high enough exec.

But as far as I can tell, it is within legal bounds for a business to freely give and taketh away free accounts if they wish. The only thing stopping them from mass account deletion is public perception.
