I moved into the adult industry years ago when the US government got involved in the online gambling mess and dwindled my profits.
I have been working in adult for the past 5 or so years now. I can tell you that now is not the time to be moving your interests into that industry.
I am again looking to find new stuff to focus on promoting. With all of the tube sites, file lockers, etc it is nearly impossible to make sales.
I mean I still make six figures per year promoting adult but my overall profits have dropped 50-60% over the past year or two.
This is not a problem with my own personal promotions. Simply hit up any of the adult industry forums and you will see that everyone is hurting for sales.
If it is a quick out of the box solution that wont take much time and effort – go for it. However if you plan to invest A LOT of time and effort into it, I would re-think things a bit.
