Another option of course is to use static IP addresses. However I
can think of only one ISP in the UK who does this as standard.

[Nigels Comment Snipped and replied to One Item]

Are we discussing ISPs or Free ISPs? I think there is a huge
difference. I pay my ISP monthly... they have a billing address for
me and my bank details. If they wish to contact me they can. If I
caused trouble they can close my account and refuse to set another
one up. However if the only verifiable detail my ISp has about me is
my CLI number then it's a great deal harder and the measures that you
suggest are reasonable.
