Cool. Now I can subtly influence you to pay for your free use MILF porn. Or use MILF models in your ads to make you more likely to buy shit.
Even if you don't think you can be influenced by that stuff it still likely to change your behaviour just enough, even just 5% more spending which makes it worthwhile to them.
But honestly your data barely matters on its own. But once it's merged with everyone else's....that's when it's valuable.
