Friend of friend of friend told that somebody he knows was arrested in Europe and extradited to USA with fraud charges. Initial sentence prosecutor was asking was something like 30-40 years. Recently I find out that this guy's sentence was reduced to 8 months for cooperation with FBI (and on top of it he have to reimburse some pretty significant amount of money to US government or something like that)...

So... Not that bad if you start cooperate with FBI. I would expect most of LulzSec gang to be disclosed pretty soon (except ones, who had enough wise to not disclose their private info to this guy from article)
