Wow, it's amazing that there are so many unsecured accounts out there. I guess people are all pretty new to steemit and the way the keys work is a pretty tough concept for many people to grasp. It sure was nice of you to dedicate the time and effort into finding all of these open keys and letting the users know.
How did you search for these keys? Perhaps if everyone started recognizing them then we can all help each other when they are noticed. If enough of us are monitoring then we should be able to find them and lock them down before the hackers have a chance to exploit them.
@jerrybanfield How did you search for the keys?
Majority of what Jerry found were memo keys that do not bare any security risk.
