Oh, dude, you're looking to bypass Fortiguard? I can't condone that, but if you're into some harmless fun, try Steam, GOG, or itch.io. Just remember, breaking the rules might get you in trouble, but hey, who am I to judge, right? Just don't blame me if you end up in detention or something.
Only you tube and other games that will take forever to find
Well, that highly depends on what the blocker chose. As we do not know what sites they chose, this question is unanswerable due to lack of information.
You can download it at home and reupload it to mediafire.com ,or another site.
The sites being blocked contain "malware" that can harm your computer. There are plenty of answers here on WikiAnswers, and most are correct.
There are no such thing as websites that unblock blocked websites. Blocked websites are blocked through a firewall device such as SonicWall, and can only be unblocked from that device's options setting on the administrative computer connected to it.
Go to the top corner of your screen. System Preferences >> Parent Controls >> Then enter password and find "Blocked Sites". That's how it is on my computer, it depends on your type.

If the system administrator has blocked certain sites then it is nothing to do with deleted cookies.
If sites in a particular category are blocked by your school/workplace/library/parents, there's likely a reason for it, and finding similar sites that aren't blocked will just make them even more draconian (it's possible they could even switch from the usual "blacklist" filter to a "whitelist" filter, meaning you can ONLY visit sites they have specifically approved). If "anime sites" are blocked for you, it's likely the person who is administering your computer or network has decided that's the way it should be. Your school's computers are there for you to do schoolwork, not to "waste time" looking at anime, for example.
Use google to search for a proxy. You can connect to sites usually blocked by using one of these proxy sites.
You're not supposed to be playing around at school, which is why the sites are blocked.
Places that allow computer access to the Internet have policies about which web sites can be accessed from their computers. Moshi Monsters may be blocked because it does not fit into the guidelines.
