Thank you for posting this information
we need to remain vigilant!
This same week i was reading a post in steemit, it had a catchy title, once in the post there was only a picture and a link to the article in a page called "steemiit.tk/" the UI was like the one on steemit, but once there the log in window appears, only option was to enter the log in details, ESC or clicking outside the login window did not work if you wanted to read the article then you had to enter the log in.. good thing i saw those "ii" on steemiit.tk, and also the .tk domain made me realize it was... a scam. First thing to do was to warn others in the comments section, it was nice to see someone was ahead of me warning everyone, thanks @felander :)
probably that account got his master key stolen by a scam like the one here, or other!
