You guys gotta understand that this isn't like a real show where enough outraged viewers can call the sponsors and have them put pressure on the makers. None of the advertisers is a big enough name to have their reputation "tarnished" by sponsoring a con man's internet show, and even if they were, the viewership is basically nonexistent, so who's going to see it? If you call them and tell them about the scams, they'll just think, "oh, I didn't know that, and next time he calls me for money, I'll say no", and he'll continue showing their ads whether they're paying him or not, because having sponsors is worth more to him (since it provides the appearance of legitimacy) than it is to them.
This is like the local hardware store sponsoring a little league team. Calling the hardware store and telling them that the star player was caught cheating in school does not make them go into damage control mode and have their name removed from the uniforms.
Still, it makes sense if this community is ever going to mature to start making their voice a source of power to the commercial, retail, and services side of the Bitcoin market. If anything, it does them a favor by not getting them involved with a conman.
