Watch out for https://2hide.net, we had a student being bullied for the URL because websense would allow it through...
As an ICT tech I feel at the sharp end...
We use websense filtering and for the most part it's OK, keywords of proxy/proxies are blocked with netsupport school on every computer that the students can access. Thus we can control, if teachers would actually bother of course!
We get our "students" to sign an AUP (internet access letter), which has to be countersigned by the parents. It's deliberately phrased as a legal contract between the school and the family. Do the students take any notice of it...do they hell!
Their homepage has the AUP plastered on it not one will read it, I guarantee you, they bring up the homepage (our intranet site) and skip straight to google.
Our new intake are waiting for their internet access to be released. We've also supplied e-mail accounts to all students this year as it has apparently become part of their ICT curriculum...has meant a new mail server with exchange 2007 and we are still ironing out the creases. This of course means that their e-mail is accessed through https as they use the OWA site rather than outlook, as is the access to the school's VLE through https. Any student who abuses that e-mail privilege loses the ability to use it, and we have had them on the first day abusing it!
The main problem is, in my opinion, it comes down to enforcement, the staff do not want to "rock the boat" or "...endanger the student's enterprise". The fact that that enterprise consists of hacking, proxy avoidance, games playing, malicious use of the e-mail system and essentially doing as little as they believe they can get away with doesn't mean a damn thing! If you listen to some of the arguments that take place because a student who wants to send e-mail has had the OWA site blocked by netsupport by the teacher, the language could turn the air blue! One student today point blank refused to do ANY work at all because his internet access was being controlled by the teacher through netsupport.
Believe me...I thank the powers that be every day that I'm not nor ever want to be a teacher!!!
The students course realise that nothing will be done if they break the ICT rules and thus know that the AUP is worthless! Even when we do try to enforce it we end up with a earful from all directions.
It was different 2 years ago as we could remove internet/network access from anyone caught breaking the AUP, now we are told we can't! One 6th former last year lost all network access due to showing other students how to use a particular proxy site, this year it feels like we'd be clapping him on the back for his initiative!
