I'm not sure if this will help anyone, but I was completely scammed yesterday by someone claiming to be OgNasty. 

I was doing a BWK for BTC swap and someone suggested using OgNasty using the following link (now dead):

https://bitcoirtalk.org/index.php?topic=303281.0

It was an exact clone of this page (with history from 2013, etc.), except it linked to a telegram with someone with the username OgNasty.  Needless to say, I got screwed out of 2.1 BTC.  I am just hoping that this helps someone - please be very careful out there - i thought i was being careful...
