I'd prefer to implement blocklists that law enforcement can maintain and
participants can optionally opt into. Law enforcement agencies can then opt
into maintaining blocklists of content they consider illegal (e.g. child
porn, copyrighted movies) and peers who are acting in good faith with their
particular country's law can opt into these blocklists as well.

This is the best compromise I can see as far as giving people on all sides
assurances that the system will be used for Good and not for Evil. ;)

That said, such blocklists can easily be evaded by adding a convergence
secret.
