I set up a webpage called [someone i went to high school with's name].com on my own time from home, put a picture of him on it, and nothing else. Albeit, it was a funny picture. I got called to the principals office like a week later and told that i had my internet permissions removed.
Unfortunately for the retards that manage IT at my high school, they forwarded all your traffic through a proxy to handle permissions. By changing the proxy settings to direct or a proxy of my own, you'd get around it... oh, and they had temp/temp1 temp2/temp2 and temp_ad/emp set up as active users too...
Edit: also net send for the lols.
