Interesting. I guess it is not a problem until it is. It is inevitable, in not already happening, bots are scrapping data and running analytics to extract asymmetric info. I suppose once this is exploited, it will be an issue worth fixing.
No, i think lots of people think it's a huge problem, but they haven't put their resources behind it to find a solution.
This could work as an approach. TBD. https://simplex.chat/#how-simplex-works
