I have spoken with a few other sex workers who have done porn. Sexyjobs is NOT where you want to be "found."
If you really want to do porn, show your interest to actual agencies and send portfolios to them directly. Do NOT go on any forum-type craigslist shit because you will have absolutely no one looking out for you. A proper agency will have your back, help you get cast, arrange travel, communicate with film producers, etc. Many agencies also keep on-staff physicians for *mandatory* STD testing and other ailments.
