For one thing MTU and those of us here that do most of the helping, do not condone piracy and try hard to discourage it. Most of those who do pirate usually do not want to be known in here.
As long as the venue owner pays to required fees up front for their use of the music then it usually isn't that bad. It is the ones who don't and are visited who have a higher fee to pay or face court. That aside as it sits those fees are the venue's responsibilty. I have never heard of SESAC ever bothering with the KJ himself. That would be the KIAA. These are the people that will want to check the legality of your music.
I did find that KIAA has expanded their website and are trying to help the legal KJs and venues to stay this way. Their web site is
http://www.thekiaa.org/ and there is a very interesting flyer they have done up that will possible help those of us that are legal to weed out the pirates. It is located here
