there is little reason to not believe the post was actually (maneater) Luka Magnotta. For a portion of 2010 he was posting similarly in various forums, bodybuilding, car forums, all varieties of things and in a similar fashion. Like he was trying to brand himself and get the world to take notice.
I was the only one who responded to him here at the time, not having a clue who the dude was...but kinda mocking the narcissistic approach. Hindsight has found many similar posts since, and a look back from those that knew the guy irl, he was definately a monster in the making.
