You are correct.  However, this is a clear attempt by "Durr" to manipulate the market to his buying advantage ... even if it is a long shot, it didn't cost him much to do it.  It isn't so different than the issues with truth and lies going around Yahoo Groups to manipulate stock prices in the years leading up to the DOT COM collapse in 2000 [so many attribute it to 9/11/2011 as the needle that popped the bubble, but fundamentals of the entire market were clear to me, a total stock NEWBIE in 2000, that prices were way to high for my own company, which was PSINET at the time [so I didn't buy options like so many of my co-workers did], and the price fell from over $50 to less than $0.25 very quickly and was delisted BEFORE 9/11/2001.  It was over and people were just starting to see it like the coyote who runs off a cliff while by chased by the road runner and then just sort of hangs there in mid-air with a "GULP" and then drops. 

In the real world, MtGox would be done, dead done, nailed to the wall and executed [meaning criminal proceedings, senate hearings, prosecutions and convictions .. well, in the US anyway].  However, this isn't the real world, it is the virtual one and people act very irrationally here and the market is very small and there is no regulation or law broken [other than by the person/people that committed the crime].  So, I don't predict the demise of MtGox, but nor do I dismiss it.

People like Durr though, should take a leap.
