A very contemporary, present topic I think......

CONTEXT
In any contemporary western country with the rule of law, we have legal rights and protection whenever somebody violates our right to confidentiality....your credit card company is not allowed to take your personal details and spending habits and attach your name to your that data on their website, for example. If they do, there are legal recourses. Most of us would consider that a legitimate law of the land not in violation of God's Word.

SCENARIO
Confessing Christian A (taken to be a brother) makes a theological statement within a confidential arrangement like a private server environment (I mean a legally binding type of confidentiality agreement or non-disclosure agreement, not a public server) to another Christian B and Christian B believes wholeheartedly that it's heresy. In this environment, people are accustomed to putting their thoughts out there, sort of a Christian discussion "sandbox", forum-type environment.

QUESTIONS
Given that Christian B is bound by their contract and by the legitimate law of the land, does the Bible reveal laws or commands which release Christian B of those confidentiality restrictions?

If so, is it a complete release? ie is Christian B given a higher duty (or right or command or obligation?) to release Christian A's statement all over the internet for the world to see and expose him?

The Bible speaks of discipline for heresy on the one hand, but also to be in subjection to the legal power.

What, if anything, are we bound to do by Scripture?

What are some things we should consider?

I posted my thoughts on this on my own blog (not here for hits but will give it out if asked) but I wonder if I'm on track so would like to hear some thoughts. And thanks for posting any!
