I'm sure the steem team can nail this theif if they take the time? The amount of skilled people involved in this platform makes me sure the theief is only able to get away with it if we let them? Steemit def needs more user friendly security as soon as poss, otherwise as this platform increases stories like this will
increase tenfold as less web savvy users sign up and it will bring the platform into disrepute. Good luck! Upvoted and resteemed.
