Qualitynet have updated their block page so if you go to say playboy.com you will get the following message:
And this URL:
https://blocked.qualitynet.net/blocked/index.php?cat=0
Now if you change the last number from 0 to say 1 you get a different message for example go to:
https://blocked.qualitynet.net/blocked/index.php?cat=1
You will notice a message added which is “Category: Pornography”
If you replace it with a 2 you get:
https://blocked.qualitynet.net/blocked/index.php?cat=2
Category: Gambling
Got it? Well this is where it gets interesting, if you replace that number with anything from 4 and up you get LOLCATS!
For example I replaced it with 19:
https://blocked.qualitynet.net/blocked/index.php?cat=19
And I got:
An ISP with a sense of humor, pretty cool.
Thanks larogue for discovering this
Update: It no longer works, Qualitynet removed the lolcats đ
