Cybersquatting on a wordpress.com domain

I’d be grateful for a bit of advice.

A Dutch colleague of mine, Jona Lendering, runs a classics website. For some reason he’s annoyed some Iranian royalists, who post attacks on him from time to time.

I notice that jonalendering.wordpress.com has been registered by one of them. It has no content: the only input is to edit the title of the default post to “Jona Lendering: Pseudo-Scholar and Conman & His Helpers Exposed”. The rest of the “site” is boiler-plate. So it’s just using wordpress.com to host an anonymous personal attack.

It’s a small thing but … is there any way to get this sorted out? Anyone got ideas?
