Well at my school it was as simple as using a proxy to get around the web blocker. Until they figured out how to prevent people from entering proxies like 3 years later, it was a sinch. I just ran my own proxy server at home so I could pretty much use my IP at school as a proxy and bypass the filters. Only me and a very select few of my friends used it though, which was great because most proxies are horribly slow, but since mine was running off my home connection it was nice and speedy even with 3-4 people using it at once.
Also there was an administrator account at school that I had access to because my keyboarding teacher loved me. The bad part was, the desktop of the administrator account was solid red except for the word "ADMINISTRATOR" in big black bold letters right in the middle, so I couldn't really use it for anything without risking serious troubles.
I couldn't read the attachment, but I saw what you meant from the link. How do you get your rank up? Play more games, and have a better overall ranking?
