From The Register:
Although Martin K. doesn't have access to the Internet - presumably to prevent he and his fellow lags from buying DVDs of Escape from Alcatraz online - he managed to file his stories through people visiting him in prison.
The blog itself isn't particularly controversial. Martin K. basically describes life in prison with no reference to his killings. But what has aggravated many is that it offers premium content. To access any of his police dossiers you have to pay, listening to a distressing phone call from a witness of one of his killings. Accessing a picture of his victims requires a fee too.
Some Dutch blogs have copied the premium content and made it available for free to prevent Martin K. from further profiting from his site. As none of this material is copyrighted, there is little he can do about it.
I really don't have a problem with prisoners earning money. I'm a little leary of a prisoner using photos or documents from his or her crimes to earn that income, but overall I think its a positive thing.
One caveat on that thought, however. Any income should be directed to restitution for the prisoner's crimes. Allow the prisoner to keep a stipend (say 25%) but the rest should go to pay for the damage the prisoner did to society. If a prisoner should pay off his or her restitution (not likely to happen, but maybe) then he or she can keep the income, subject to ordinary income taxes of course.
