thanks for this dom..
i guess this shows that perhaps we should all be registering derivatives of our URLs aswell as personal twitter accounts if we want to keep them safe?
this page on twitter might also help, they seem to be pretty proactive in removing folks who squat on other folks urls and company names etc http://help.twitter.com/forums/26257/entries
i guess if you can prove you own the domain, you can get the user who registered it “for you” blocked or at least let the twitter folks know about it
i guess this wouldn’t be a new thing though, i presume other sites like facebook and myspace have had similar probs in the past?
