In some cases, where students have utilized the internet to spread rumors and harass their contemporaries the school has actually interceded and pulled transcripts off of the websites as proof and justification for the punishment of the offending party. Teasing and harassment is no longer limited to the halls; through e-mail, AIM, Myspace, Facebook, and blogs bullies now have a variety of ways to attack their prey. Speaking from experience, I had a friend post a picture of the girl her ex-boyfriend was currently dating on myspace, she called the girl a "gremlin" and a "hoe". To me and my group of friends, the posting was funny but i'm sure that to the girl it was humiliating.
This is just one example of how blogs can be abused (and commonly are), especially in the high school setting where teen's insecurities are at their highest.
