I honestly don't believe that. (How could you or Facebook prove that?)
I deleted my account a few months ago. However I have no way of verifying if all that data is gone for good, overwritten with some new persons data to sell to marketers.
But the reason I deleted my Facebook account is because I just don't trust Facebook.
One way to 'prove' that would be if Facebook can support such claims in legal documents or terms and conditions. Well technically it's not really a proof, but I will accept it.
Maybe it's time to institute outside audits on these apps. That would be a useful direction for something like the BBB to move into if they want to get out of the extortion business.
