Great post. Here's a few tips for other blackhatters getting their feet wet with CPA networks:
The reason people say you should run incentivizable offers is because with a method like this, the conversion rate will be incredibly high. With incentivizable offers this doesn't matter, but with regular offers you will attract attention and most likely you will have your account banned. This has nothing to do with blanking the referrer - you're allowed to do that, as CPA networks can't legally demand to know where your traffic is coming from. Merchants don't like it, but they can't do anything about it.
If you can't find any incentivizable offers, then you should consider buying junk traffic in order to get your conversion rates down. Aim for a conversion rate of 1-5%. Anything more than that, and you risk getting banned and losing all your commissions.
I work closely with CPA networks and have made good friends with quite a few AMs, and as a result I have pretty good knowledge of how they operate. So if you have any questions, I'll be happy to answer them.
