Well, we also installed a new server. And on that server is a filter that blocks off certain websites as chosen by the system administrator (a teacher).
Before the new server the only things that were banned were some obvious scam sites, tor, porn sites, etcetc, like all the bad stuff.
So I casually try to go on gamefaqs today.
>Banned
...okay I thought, how and why does he know about gamefaqs, moving on
turns out that 4chan and newgrounds also got banned, as well as 90% of all proxy sites I know (well except for one that connected to a server in vietnam and took about 15 minutes just to load 4chan)
>mfw I realize our teacher knows about 4chan and gamefaqs
>mfw he banned them
