One of the reasons I deactivated my account on FB.
And the fact that even if the photos were of any interest to anyone (for news, or generating money from rights etc) - the owner doesn't stand a chance in having them back (as Facebook has full rights to the images even after you deactivate your account - and they are all still saved on their servers)
If someone else posts them, then deactivating does nothing??
You could be person A with no social networking accounts. If person B posts them online, then they are for everyone to see.
