His OTC rating and activity on this forum were mostly run of the mill small loans (both giving and receiving) and selling of items. I did some perusing when another forum user said they figured out what he was doing by being open minded and looking through Pirateat40's bitcointalk history. Personally, all his history told me was when he started accepting bitcoin accounts he may have been loaning out bitcoins at high interest rates in much larger volumes than he could handle personally. But the question there is how was he able to maintain such a consistent rate of return. The loan business, especially at payday loan style interest rates, isn't known for 100% payback rates.

GPUMax was introduced later than the interest bearing accounts yes? And is structured such that it could be used to "clean bitcoins"? I haven't personally researched this but I may now that I'm a bit curious. If the aforementioned questions have affirmative answers then I think it raises more questions rather than add to Pirateat40's trustworthiness.

Next few weeks should be interesting.
