Yep! Even since 2016 (at least to my knowledge, probably farther back) people already know trading on LBC gets them in trouble. I'm not sure using other p2p platforms help them, end of the day cash transfers and money transfers, once they start happening regularly, puts up very big red flags.
Guy also did it in 2012, he also admitted to them, so they're probably taking all that into account for leniency. Not sure people would get away with less should they get caught doing the same things today.
It might also have something to do with the prosecuting party being FinCEN as opposed to the FBI. I'm not entirely sure about this, though, and it's only speculation on my part.
At the end of the day, regardless of what seems to be leniency from the regulator's part, it doesn't mean that everyone will get away with the same sort of treatment, because previous cases of similar nature we can confirm resulted in imprisonment for some.
Just make sure that if you are indeed regularly advertising on p2p platforms, and dealing with commercial volumes of BTC all the time in your transactions, you are aware of the regulations and reporting obligations. Otherwise you could land in trouble.
