 :The material you and a lot of others posted might very well be considered vandalism, please read up WP:ENC. The question is not really whether you want to disgrace the school or not but whether what you have added to the article is is notable, referenced and encyclopedic. A lot of such incidents happen in almost every school but they don't fit in an encyclopedia. I am sure there are a lot of other forums on the internet where you can post such stuff. I think what you did was more due to ignorance than a deliberate violation of rules. So, please read up on wikipedia guidelines.  
 :PS - Even if you add saying 'Anonymous' on the page, the username shows up on the history page anyway, so there is not much point. )  |  "
