No. If you uploaded something to Safenet and decided to let everbody read it or download it. Nobody could ever remove that data no matter what. Just not possible. And you, the uploader can never be found either. And you could also charge people SafeCoin to read your data if you want. Nobody could stop that either, and nobody could find who you are, even if you keep updating your wesbsite and keep making money on it.
Thus, in my opinion, if SafeNet manages to reach its goal and it actually works as promised. It will be very popular. And the demand for space for people with good business ideas will be huge. They are going to want safecoins so they can upload all there stuff to SafeNet and start making money on their ideas.
