I know a lot about this guy. I won't name names because of dox, but there are some interesting facts about what he did:

• He targeted female streamers almost exclusively, for very sexist reasons. He would threaten to swat them and their families if they didn't give him nude pics. Some girls did cave to the pressure and he accumulated a collection of child pornography because of this. (this is not the girls' fault)
• At one point he posted child pornography to his Twitter account. He also shared it with his friends.
• His father has a long rap sheet of violent crimes
• One of the ways he targeted streamers was to obtain their home address by offering to buy them pizza. After befriending them for info, he would become abusive.
• His tactics were very "pick-up-artist"-y. You would say he had "game".
• He engaged in long term harassment of several female streamers and shut down a number of streams, both via ddos and by causing them to burn out.
• He did not commit these acts alone. He had a number of people helping him. For example with the ddos and the doxing, he didn't do that alone. The people helping him were not arrested.
• He used to host a github containing a number of tools for getting streamers' IP addresses, emails, a streamer target list, and encrypted child pornography.
• This guy does not represent the average gamer or the average male for that matter, but he has had a corrupting influence over the many male gamers who observed his actions and how much attention it got him. He educated many of his friends in how he did what he did. The ability to exert control over females is very alluring to some.

O******** is representative of a particular niche of subculture(not strictly gaming) where the real dangerous sexism and targeting of females comes from. If you are female and popular, you will be targeted. You will be targeted in ways that will cause shame to prevent you from speaking out. It's a sad world we live in but it is the reality. Please be careful.
