It always puzzled me how all personal information is visible to everybody on Steemit, the explaination being "well, thats the way the blockchain works".
It goes against just about everything people are demanding in the context of internet privacy. Remember how people complain all the time, about Google knowing where you are, what you buy, what your credit status is or even your bank account? And how the politicians debate about laws to prevent total transparency?
Well, here on Steemit nobody seemed to worry about this - until your post come out.
Of course the wallet should not be visible to everybody. But I'm not sure how it can be prevented, concidering how the data is stored.
