These are instances of private companies acting like governments. What characterizes private companies is that they do not use coercion (except of course when it's justified as in enforcing voluntary agreements and protecting property.)
So for example, the original post was about banking regulation. Private bank regulators could not force banks to operate according to their standards. Instead, they would rely on banks' cooperation. If a bank did not cooperate it would run the risk of being rated badly and shunned by customers relying on regulator's rating. In no case would a non-cooperating, non-conforming bank be subject to being "killed, enslaved, tortured, kidnapped, etc" by a private regulator. On the other hand, a bank which does not conform to government regulation is in danger of killed (dissolved) and its officers "enslaved, tortured, kidnapped, etc." (arrested and imprisoned.)
