This stuff happens every time with people that have mental issues. "He seemed like such a nice guy!". "I never saw him lose his temper!".
Of course, none of that applies to Utnayan. Utnayan was always someone that could be funny, could be hilarious, but always had this clearly unstable deranged side. You have been on this forum dude. Take a gander at any of the Curt Schilling threads, . His trolling and accusations there were completely over the top, clearly delusional, and yet he kept it up for fucking years. "Inside info", "secret sources", binders on people, accusing fucking EVERYONE of being a shill for companies, even people that have been on the forum for a decade. He only "escaped" some of the ramifications for his breakdowns in those threads because people saw him as "right". That was always nuts, as if finding some evidence that a scientist faked some global warming thing would somehow excuse all of Lumi's craziness over the years.
