   @liw @emacsen In the system we're describing, nobody can make someone remove things though, it can only be voluntary. Of course, this turns out to be true of any distributed system (or even non-distributed system).

   Though I think most removal happens through "natural GC" (nobody cares to keep it around anymore).

   Systems that can't be garbage collected worry me more than systems where things can't be force-deleted, since we can't really do force deletion anyway...

     @cwebber @emacsen Good point. Let me try to pontificate a bit more.

     Systems like traditional PGP keyserver networks, where anyone can upload signatures, or Bitcoin blockchain, where too many people can upload, say, child porn, and it can't reasonably be removed, are problematic. I'm less worried about whether removal can be forced against objections, and more worried whether the system is ready for it at all.

     @liw @emacsen Yes, I agree with that. If the system cannot support *cooperative removal*, then it's a big problem.
