Probably not, but it has happened. For example, in Costa Mesa, California, 20 middle school students were suspended for visiting MySpace.com, where one of their classmates had posted a graphic threat against a fellow classmate and invited others to sign up to take part. [1]  We know of no specific policies about MySpace or similar sites in D.C., Prince Georges or Montgomery County schools. Montgomery County has blocked access to MySpace from school computers.
