In theory unless you’re validating each signature external to the client, they could also be signing arbitrary events and saving them for future blackmail or info war. It would be great to have an external super quick and easy 2FA on all outbound signed notes. Does this exist?

Granted, there's a lot about Nostr being censorship resistant that I don't understand. I'm trying to work this out. How would a client benefit from censoring? If your content is being written to multiple relays, then those relays would, in effect, be censored to the extent that your content is written to them, right? Wouldn't this make the censorship stand out? And since there are multiple clients anyone can use with the same nsec, then anyone could easily document with near certainty the offending client. Right? So if it's that easy to identify censorship, wouldn't it be the kiss of death for a developer to try it on a freedom platform like Nostr? I don't see any upside for a client to censor. All I see is a dying brand if it's tried. If I'm not tracking here, someone step in and correct me please.
