Thank you for taking on this challenge @reazuliqbal — it's a much needed initiative, and as Steemit continues to grow, I expect we'll only see more and more "black hat" actors come in to try to nab users' wallets.
I hope this tests out successfully. As I replied to Asher in a different post, there may end up having to be a "version" of @noblebot that pings each of the different front ends... they all seem to handle keys and permissions a little differently. I say that just as the observations of a user, not as a developer... I have NO idea about the technical end.

Thank you so much for commenting. @noblebot is still under heavy testing in real life situation. Yes, blackhats may increase as we grow more and more, but I hope there would be some whitehats too.
Front-ends are just the front of the Blockchain, they all treat keys the same but its true some may not warn you before posting private keys others may do. So, we just need to petrol the Blockchain.
