Don't know that much about him but he just seemed like an eccentric, unlike other notorious internet figures who are either mentally ill and should be in secure care (Daniel Larson) or are horrible people (DSP)
That video from his dad is brutal. Guy was bullied since he was 3 years old. I remember watching a video about his bizarre internet presence a few years ago and he seemed like a good egg, just a real eccentric. RIP.
