From the whitepaper:
I may be misunderstanding how this protocol works, but at step 10 what prevents the owner from publishing the captcha answer as incorrect as a method of censorship based on the content of the post?
nothing prevents it, the sub owner can put a challenge that's impossible to solve to troll people. it's required that this be possible otherwise the sub owner wouldnt have full control over what the challenge is.
a lemmy instance could do the same thing so it's not really an issue, the fix is just dont use subs / instances that dont work.
