It also shows a willingness by the system author(s) (me!) to provide
solutions to their problems. I'm open to better suggestions! Sacrificing
deduplication in the case people don't wish to provide a convergence secret
is unacceptable to me.

*shrug* IMO that's their problem, not mine. There is absolutely no
technological solution to blocking "by category" in a system like the
Cryptosphere. A content ID-based blocklist is the best solution I can
personally think of. I'm open to better suggestions that don't involve
abandoning global deduplication
