NTL is a big cable ISP in the UK. Each proxy serves tens or hundreds of thousands of people. Anon editors all look like the same IP. Therefore, when blocking in that range, make the block really short, so as to help avoid collateral damage. Also good if you keep your Wikipedia email working for notices of collateral damage.
