Heh, i love how all these self confessed computor science law and human rights experts suddenly appear at the thread like this.
Fact is, non of us are at your uni and non of us have read a detailed copy of your accomodation contract. Theres no point asking us if your allowed to do something or not.. go read your damn contract.
It is my guess your contract will refere to a 'terms of use' located on your university website somewhere which will list exactly what you can and cant do using the university connection. As you are renting the university property and using the university internet connection you must adhere to their rules as stated in your conract, so if your contract says 'NO PORN' then guess what... YOU AINT ALLOWED PORN.
Its just that simple!
Human right to look at porn? Awesome! But not true, you do not have a human right to use any internet connection you please to obtain any infomation you please. Im sure your university will 'retain the right to refuse use of computer services for any or no reason' etc etc, which means they have the legal right (legal because its in your contract) to cut off your university internet for any or no reason.
People - Please stop asking dumb questions on the H + R forum for which we have no chance of being able to answer because we dont have knowledge of your contract/relationship/living circumstances.
