My opinion is a little self-serving, but I think if more copyright owners sued pirates the problem would drop dramatically.
The vast majority of people that like porn don't regularly throw a brick through the window of a brick and mortar adult store because there is a good chance they will get caught and punished. There are still a few idiots that will break into a store to steal, but you cannot eliminate stupidity, just reduce the occurrence of it in your life.
If more copyright owners would start enforcing their copyrights, then the vast majority would realize it is not worth the risk. Right now, copyrighted material can be stolen on the internet with little risk of repercussion.
I can drive down on the Phoenix highways at 20 MPH over the speed limit with little fear because I know the enforcement is pretty relaxed. If I drive down the highway and every mile I see someone pulled over, I am going to drop my speed down to the limit.
I really don't like to have to sue people. I am not asking for more business. There are other lawyers that like to file copyright lawsuits and they are good at it--go to them. But seriously, GO TO THEM. Don't accept the status quo. Plus, do all the other things that have been suggested in this thread.

I just wish content providers and webmasters could unite for a common effort to reduce piracy but expecting adult content providers and webmasters to agree on anything is a stretch, especially when it involves putting money up front.:juggle:
