I did mention this several times before, but if it becomes hard or annoying to keep finding new proxies (most likely because they are getting blocked), there's always Tor https://www.torproject.org/

If you can, just put it on your USB (it's fully portable) and set the network settings to your school's ones and it should work! You can get it with portable Firefox which is even better and enjoy unrestricted browsing!

If anyone decides to try this, tell me, as there are some extra settings I might need to tell you about.

Keoni, it is. We have an arcade, and the forums provide "social media"-type functions

I tried at my school on Monday. Omnimaga is blocked. But as far as I know, nobody has used it! But it's not that bad, because Google login pages are blocked, yet I'm still logged in... so I can probably bypass it. But really, what harm can Omnimaga do?!

I just noted that the websites metatag contains several references to gaming.
Maybe this causes the software to add it to a blacklist.

Yeah the meta data has game-related stuff in it. I wonder if removing them could actually hurt our traffic, though? As for an alternate address I doubt this would work, since they would most likely block the entire IP.
