I agree with IcicleDisaster. If you are correct, do you want to make your boss look like an idiot?
As for this guy’s record, are you tracking any of the results? You can’t say if he’s doing a good or bad job without any hard data. I just did a brief skim of moneybot and it creates web2.0 links, a common backlinking strategy used by many SEO companies. Some people consider this grey hat and others black hat. Technically, all link building strategies are blackhat including the ones that you might consider white hat.
It only really matters if Google decides to penalize you, which most likely will not happen. I know someone that’s been using web2.0 links for the last 15 years and they’ve received no penalty to this day. They did however, lose their top ranking spot because more competition moved in the area willing to pay for bigger budget links. Web2.0 only works in smaller less competitive markets.
If your guy is above average, he would be smart enough to direct the links to a domain that he controls before juicing up the money site. That way you can remove any future penalty.
