Well they can feck off!
I already pay tax to use the internet in the form of VAT on the services and equipment I hire from NTL.
Is it my fault I get so much spam?I have to pay to sort it out.Now if I was to purchase a spam filtering product from my ISP and part of the proceeds went to setting up third world Internet technology well that's a different matter.
I'd be getting summat sensible for my money whilst doing my bit in all directions.
