The issue of teens taking naked pictures of themselves with their cell phones and sending them to other teens has been an issue of increasing concern , with teens being slapped with child pornography charges, simply by virtue of the fact that the subject of the picture was under 18 -- even if the photographer took the picture him- or herself.

However, now there's a case where the pornography charge may be justified: An 8th grade boy in Massachussets allegedly sold nude "sexts" of his 8th-grade (presumably, now, former) girlfriend to his classmates for $5 apiece, according to press reports .

The picture may have been forwarded to as many as 40 or 50 students, according to the Boston Globe.

While there have been sexting incidents at the middle-school level in the same town, those pictures went to just a couple of students and were dealt with through a cyber-education program and community service, according to the Belmont Citizen-Herald, which broke the story.

A study by the Associated Press and MTV found that about 10 percent of students reported that they had sent nude photos on their cell phone.
