Ask HN: I registered a domain that has a Twitter account assigned to it

I just registered a nice domain name for a new project. Let's call it xyz.com. The domain was free, but has been in use before.

I noticed the twitter handle @xyz is registered, has a text and a logo of the project that previously was on the domain. It has not twittered anything though. It has a link to xyz.com in its description and it is assigned to mail@xyz.com

What would you guys do? Just reset the twitter password and use it? Try to contact Twitter? Try to contact the previous owner? So far, I was not able to find any contact info.
