A friend of mine that I actually coached on AdWords and Overture owns a few of these "napster of porn" type sites, and I gotta say, rule breaking doesn't apply when you are pulling in nearly six figures a month. His overhead also adds up, so don't just think hes making bank without spending a lot of it. But when it comes down to it, it's 100% worth the time, cash, effort, and problems.
So a big
to him and all the other guys reaping the benefits of being creative.
