Law enforcement definitely has the information on passthrough programs and they know Og was involved.  They probably didn't go after him because it wasn't that much money.

OGNasty was basically picking up the scraps compared to what Pirateat was doing.  His pitch was basically (and I'm paraphrasing here):  "pirateat is an asset to the community, you should invest with him if you can!  If you don't have enough money or an invite though, I'll help you out!"
