That's a fair point, you've changed my mind. However what about if such a system was voluntary? Like you could opt-out of it, or opt into it. That's how car insurance is starting to work. You can get a thing put in your car that will monitor your driving, and in exchange you get lower rates. Perhaps you could opt into the social media scanner and get lower interest rates. If you don't, you just get grouped with all the other people who voluntarily opted out, and your rates will probably not be any higher than before. And in any case, landlords and employers already look at social media profiles. It's not like that is going to go away if you ban this, but an algorithm has a chance to be more fair and unbiased at it than a human.
