Dan Cuthbert. He was trying to make a donation to a Tsunami relief
charity web site and noted that the site was very slow and thought
perhaps he might be being phished, so he truncated the URL back to just
the host name. He was prosecuted for purely that action, possibly
because as an IT professional the police thought he should realise that
such an action would be unauthorised.
