Indeed, that moneymakergroup site contains some of the biggest idiots in denial that have ever graced the internet.
Interesting side note regarding the videos:

Two are from "Jack", and the other is by "Kendall".
These are indeed names of people "involved" with Poker By Proxy (at least the names they use when communicating with its victims), but I don't think the guys in the video have anything to do with this.
I believe they are web actors, who were paid to make these messages. You can find people to do this for as little as $5 on sites like fiver.com.
I think it's likely that these web actors had no idea that they were promoting a scam. They probably just thought they were being the American faces of foreign companies trying to market their product.
There are two reasons I believe these guys NOT to actually be involved in the company:
1) They're both American. The people behind Poker By Proxy appear to be non-American by all appearances, including their "backwards" use of the date format.
2) They both speak too well. The average businessman comes off as a doddering fool when he gets in front of the camera to produce marketing videos. These guys seem experienced regarding speaking to the camera and using a pleasant, marketing-friendly tone of voice. It's a lot harder to do this than it appears. "Kendall" also does this in front of a completely white background -- something unlikely to be seen if the video is being produced by amateurs.
