I've been following Mat's post for a while now... and yes Mat can be a bit over the top and excitable, but I really appreciate his diligence in watching bitfinex. It's not only possible but entirely likely that bitfinex is doing what Mat believes they are doing. There is no reason for bitfinex not to do what they are doing... no one, until Mat, is looking over their shoulder. More importantly, there is almost zero downside risk for bitfinex to engage in these practices.
