In China, people generally share porn through closed social network groups.

Given what we know about China's internet, is there any real privacy in those groups if authorities wanted to crack down on them?

Well the sheer volume and high percetages of users that do it make it difficult. Despite what people try to pretend the Chinese government can't arbitrarily decree things without pushback and political fallout for it. You can't arrest all offenders if it means holding tens of millions people in detention. And trying to ban porn completely is going to piss off a massive percentage of their population, even if they don't say it directly.

encryption exists. so to an extent, yes there is privacy, but in the end, people are always the weak link.
