I just took a look at some of your IP s history the warning applied to Mathematical Notation does not appear to be valid from what I understand However today s warning regarding MacGregor State High School absolutely appears valid for the IP removed a sizable amount of information from the article If you did this edit and you felt deleting the information made the article better an explanation as to why in the edit summary at a minimum and in the page s discussion page would have helped identify you as a non vandal My advice is to improve your editing practices by 1 registering 2 using edit summaries 3 avoid deletion blocks of information rather than improving them and 4 invite discussion before making major changes By the way the IP vandalism tag does not hinder your work in any respect What it does is help admins quickly identify edits that may involve vandalism so that that IP can be more quickly blocked when vandalism sprees occur Good luck
