It would be very helpful to have a shredding machine that could shred the following:

- urls that go to lists of adverts
- urls and websites created by people who are never going to make 50p on the internet, let alone their fortune - but don’t yet realise this
- spam
- people who send spam - obviously the shredding machine will have to be fairly big to enable these people to be fed in either head, or feet first.
