Adult industry growing up?

[temi]

According to Symantec , adult spam mail coming into our inbox has declined significantly compared with the rate of adult spam we used to get in the past.
I wonder if this is a sign that the adult industry is either in decline or "growing up" by learning non spam methords to promote their products and services.

I think it has more to do with spam filters getting better at filtering this junk

I have an adult website which gets a lot of natural SE traffic and has high positions on competitive phrases on MSN. But it earns me nothing? Anyone here experience with monetizing an adult site?
