If you have the proper tools, proxies are a piece of cake to bypass. I just used my laptop and a computer I had set up at home. I won't say exactly what I did, though. I'm just glad my school let me use my laptop. I didn't bypass it all of the time, though (although, I also wasn't a member of a forum at the time). Technically, you can even do it with another computer and a flash drive (if the school allows you to run programs off a flash drive, anyway). I'm glad I no longer have to deal with those annoyances.
