I just saw this article and wrote a small program which crawls the blockchain and puts every block in a regex.
If something smells like a key it will check if the key is still valid (or never has been a key and is still not valid).
I still need some testing with transfering funds and posting an article for the guy, who lost his key, so he knows what's going on.
And maybe later auto payback, when they have changed their passwords.
It seems like sami100 also changes the withdraw_vesting_route.
@sadiq689, @aponamran and @maruharraca will send all their Steem to sami100 when they start a Power Down.
I don't think you can change the vesting route on steemit or steemconnect, yet. You need an api for this.
Getting a script set up tonight hopefully to get that done for them. Thanks for noticing this.
I put up an issue about it https://github.com/steemit/steem/issues/2498 Message me if you want to help with the recovery project, the more the better.
