It seems crappy country singer Keith Urban is is sueing oil painter Keith Urban for owning and using the domain name of his own name. Nowhere on his site does painter Urban claim to be a country singer, alcoholic or married to a redhead.
This is the thing about these high profile wankers sueing. If they asked nicely, they could probably come to some arrangement. For example, put a prominent link on the front page pointing to the other Keith Urban's site, for people looking for the lousy alcoholic country singer. Instead, they start out with legal letters.
So warbling country loser Keith Urban, you're an arsehole.
Oh and if you're a somehow more famous Rumble, take this as a warning. Legal letters will get you nowhere.
