You realize you can report that to twitch if that's true because that is against twitches terms of service. Now if they aren't publicly putting prices out there or discussing prices on stream then there is nothing that can be done about it. Lunas for all doesn't say $600 dollars for a recov or anything along those lines.... it just suggests they are helping people. I have friends that do recovs so I know it's out there but they are very careful about what they do/say on stream.
