Also he appears to be using a fake phone number on the WhoIs, am I right in thinking you're not allowed to do that?

Technically you are not allowed to provide fake information, although you may use an identity proxy as long as they provide the means to contact you in case of a dispute. In reality, enforcement of valid identity information is essentially non-existent.

I'm personally aware of at least one incident in which someone who had their domain revoked for 'joke' contact details in the whois db. Then again, istr they did piss off an old-school sysadmin (in the a.s.r sense).

As a Brit, it doesn't surprise me at the British address here. I work primarily with US companies but the most obnoxious service I get tends to be from the British ones. An idea of "honor above money" seems to be more prevalent here in the UK, whereas in the US it seems you're more likely to just get ignored.

It's against the rules to use false info so feel free to email contact@namecheap.com with that little bit of info.
