Ok in answer to your questions.
1) We pay for our bandwidth through revenue generated - As with any other ISP/WISP - As to our business model, I am happy to disclose all that is necessary to communities that are genuinely interested in our services. This would be done, as previously mentioned, using the normal sensible business precautions to protect our IP etc. This is NOT avoiding the question but simply not being prepared to show you our "undies" in an open forum.
2) We use our own, custom built system that manages Bandwidth on a per user basis and is able to take very good care of any "mad torrent freak" very effectively to ensure that no other user's experience is damaged in any way by the selfish users that are always out there. Again the actual system/technology is not for open forum discussion for what I would expect to be very obvious reasons.
3) With regard to criminal activity, copyright infringement etc., we are as protected as ANY other ISP/WISP out there and more than most. Again our own systems keep ample records for use at any time by the appropriate authorities and we make it our business to cooperate fully and rapidly if we need to.
Our system also, arbitrarily, blocks access to Pornography and much other unpleasant and unnecessary content on ALL of our networks - The first UK ISP to do this I believe and we are proud of it. WE believe the protection of our children is far more important than any adult's right to access content such as this.
Our Broadband links are also protected by the Internet Watch Foundation's Blocking list, we support CEOP and display the CEOP Panic button across our site, offer a comprehensive "Safe Surfing" guide and have, for example, been given a full and clean bill of health by Hampshire County Council and their Child Services team as being suitable for use by children in their schools and in their county.
Hopefully this answers all of your questions and reduces your level of perhaps understandable cynicism in this day and age.
I think your final comment is actually unfair but I guess, as I said, understandable.
Believe me, people and organisations ARE capable of doing good things and doing them well. Hopefully you can believe that one day too
