Cosmo from UGNazi got sentenced to 1 year in jail today: http://www.dailydot.com/news/teen-hacker-cosmo-the-god-sentenced-1-year/
UPDATE: Cosmo the God has not, in fact, been sentenced to juvenile detention. @vizfosho, the source who originally reported on Cosmo's sentencing, admits that the sentencing hasn't actually happened yet—and spreading the misinformation was "@cosmothegod['s] lulzy idea." For his part, Cosmo (or someone using the Twitter handle @cosmothegod) denies starting the rumor.
