IOW, "rubber hose cryptanalysis." There's not much you can do about it short of avoiding detection in the first place, which is why I'm such a big proponent of end-to-end crypto everywhere. For a long time it's been the case that the best way to your secrets is to employ meat-space tactics, from the aforementioned rubber hose to more quotidian social engineering.
Why crack a password when you can crack a human being?
Good password policy and encryption is useful for keeping out a subsection of reddit and anonymous, but at the end of the day this is a political issue (politics, defined as human to human interaction). Security only exists in trust, and as you trust networks get larger your security gets weaker. It's a hard problem to scale security because it's ultimately a political issue.
