While I'm sure this thread will somehow come back to haunt my Google search rankings, I'm glad I missed that bit of Detective GAF misfire ;D
Officially, from the Twitch perspective, this has been handled. We closed his account, terminated his partnership contract, and we'll be issuing refunds to his subscribers in the coming week. Everything else is in the hands of the people he defrauded, of which I'm sure they'll seek retribution, as they probably should.
Obvious, reprehensible behavior aside, what upsets me most about this is that Twitch has numerous, established disabled gamers, and what this guy did is a huge slap into the face to people such as Aieron, and communities such as AbleGamers, who are helping raise awareness of their causes, as well as providing positive environments for fellow disabled gamers. I just hope this doesn't affect them in the long run.
