If a concerned parent calls a students school and makes exacerbated accusation do libel/slanter laws apply?

they do not apply, mainly because itd be too hard to prove.

first off, you have to prove that there was intent to cause harm to your character.

second, you have to prove that actually happened.

with mouth-to-mouth, there is almost no way to prove slander did happen. person a could say one thing, and person b can say somtehing entirely different.

usually the only way to prove slander is to have something written in print.

this is the reason why youd be perfectly fine saying '____ should have been held back in 1st grade', while youd be in serious trouble writing the same sentence out and publishing it in a newspaper.

A thirteen year old students "myspace" should simply be deleted regardless of content. She's too young to be on the site at all.
