That would be because he's completely insane. He's been blacklisted because he's hiv+ but is one of those nutcases who believes hiv doesn't exist and it's the anti-viral drugs that make you sick. Here's an interview here

Well moreso than that might be his use of meth.

from Wiki:
Palmer currently makes his home once again in Mendoza, Argentina, having moved there in October 2009 after years in Portland, Oregon. While the move has led some fans to believe he is sick and has "gone home to die", pictures on his website from May 2009 show a very healthy-looking Palmer. He no longer performs in pornographic films, but instead hosts occasional solo webcam shows for his fans on his website.[4] He now forswears antiretroviral drugs as he believes they cause AIDS, instead promoting the therapeutic use of cannabis.[9] Palmer has admitted to a crystal meth addiction which he deals with through his belief in Jesus Christ but continues to use the drug.

Like the article says he's not looking unhealthy on his website tho:
