I'm a little surprised that you're surprised because you were banned from Reddit (or even the link removed) when you offered password-hacking services. Even if you presented it as some kind of white hack.
What if there was a wallet with 1000 BTC in it, would you just pass on the password or would you think "Why not solve my life"... Of course, you can make all kinds of promises now, but only if the situation really happened, then they would know what your intentions are.
