Avoid doing side business with anyone claiming to represent Cyanogen, for starters. I'm sure they haven't released his name at the advice of a lawyer (or they just have good legal sense). They shouldn't do anything that would jeopardize their ability to pursue legal action against the hijacker.

It's public via whois.

Doesn't have a person's name though.

Well, this conversation: https://twitter.com/koush/status/268836995890028544 has a guy called Ahmet Deveci who seems to be going at it with Koush about giving back DNS domains.

His profile on twitter says "Entrepreneur, with a passion for website design, development and all things technology. Director of Metserve Enterprises. London, UK · http://www.mradeveci.com

That seems like the guy.

Let's try and be certain before we start hurling abuse eh mobs?

That was available through www.metserve.com but the site is offline now. I assume it's related.

Anyway he is having a conversation with the CM team over Twitter.

Conversation... More like public poo flinging. I mean seriously? Use email or something, it's really unprofessional to "talk" these things out over twitter

I think at this point they're just trying to get him to talk anything they can add as evidence on the impending lawsuit about fraud.
