There's 2 possible truths to the matter.
Truth 1- This is Marg and he has posted TMI on planet miencraft.
Truth 2- This is not Marg, he has copied the text from the forum post, placing the 'n's to fool people into thinkign he wrote that, violated the copyright,and thus is viable to have his acoutn sut down due to impersonating someone and takign credit for their mod.
Reality is, there's no way of knowing unless someone contacts the Marg from the forums and ask if he's created a PM account.
