I asked the admin and he says that there's a really '
naughty' <his words not mine> phrase somewhere in the forum page that the blocker fails to let through.
It must be quite something else though because the blocker lets through a lot of profanity and such. As long as there's that phrase on the front page, G___G forum is closed to the firewall
What's funny is that 'Who's Online' was also blocked a while ago because someone was looking in the thread with the banned title... xD
EDIT: LOL, I'm using < > instead of ( ). Damn HTML classes.
