We're now accepting XFF headers from NTL proxies. This means that NTL users will now appear to be editing from their home IP address, rather than from a proxy. Blocks will be specific to a particular NTL connection. This should be a big help in dealing with a couple of really annoying NTL vandals who have been operating on en, e.g. MARMOT.
The proxy list I'm using comes from:
http://ben.cheetham.me.uk/resources/net/ntl-proxy-list
That was the most up-to-date list I could find, it's possible there are some missing. If anyone has a better source for this information, please speak up.
Big thanks to NTL for being good a Internet citizen and sending out this information, as opposed to our arch nemesis ISP, AOL.
