Comment Sure they'll delete it. (Score 2) 23
A quarter century ago I briefly dated a stripper. She needed new posters to sell, but she couldn't afford a professional photographer and she wanted control of the masters. This was near the dawn of digital photography for consumers and I had a camera, so I agreed to take them. We did a shoot with a couple hundred photos. They weren't great, but it got the job done.
Shortly after that we stopped seeing each other. She asked me for the photos, and requested I delete them. I said yes. I burned the shots to two copies on CDs and gave them to her.
I did not delete them.
I never shared them with another soul, but I absolutely lied to her. I knew I was lying as I said it. And my reasons were up front and simple. Fast forward to me today, and the only difference is that today I'd be honest about not deleting them. I would promise to keep them private.
Now these brokers have a vastly stronger motive to lie. Money. Lots and lots of it. I guarantee you data that is "deleted" is just relocated. Even if there's no immediate plan for it, it will be hoarded. And there are so many ways to do it you cannot catch them.
