While schools should certainly block access to certain sites while on school property.... why are they doing a parents job? If the child is engaging in acts that are not allowed at school or that the school thinks are dangerous.... why aren't they contacting the parents to express their concerns?

It is not the schools place to delete things on a students account (even though I do not think they could do so anyway since the sites ARE password protected) nor should the teachers be expected to do that. They are teachers... not babysitters or parents. If the teachers suspects a problem or has some concerns the parents should be contacted. BUT.... inappropriate sites should be blocked from school computers.
