Bad people will undoubtedly use available tech, but if there's no effort to protect standard users of nostr then it's not going to last or grow because the good people will leave. It's not much of a sales pitch, is it? Join nostr, be exposed to CP. No one sane is going to want to join that or stick around. Nostr.build does a lot of work, using available tools, to protect themselves and legitimate users. If relay operators don't adopt some sort of similar techniques they'll not only be failing the community they support, they'll be leaving themselves open to claims of liability. What really concerns me is that I'm only connected to a handful of standard relays that loads of people use. It's not even like it's notes on some random outlier relay that no one else uses.
