IT experts trying to trace the person who put a sex film featuring a young Dutch woman online say they have traced a key IP address on Facebook’s servers in Dublin.

The IP address is registered to a small company named ITWorkz, which is part of the Noord Brabant ROC trade school, the Telegraaf says on Wednesday.  The company offers IT services and IP addresses to educational institutes in the region.

The Facebook account used to upload the film was probably made using that IP address, the paper says.

Lawyers for Facebook and the revenge porn victim agreed in March that both sides could investigate who uploaded the video, after months of legal wrangling.

The video was uploaded last January by a fake account bearing the name of a young Dutch woman named Chantal. Facebook failed to comply with a court order to reveal who set up the account last July, claiming that the data disappeared.

After a judge determined there should be an independent investigation, several months of legal bickering ensued. Chantal wanted the research carried out by Dutch forensic IT specialist Mark Hoekstra, while Facebook wanted it done by an Irish investigator of its own choosing.

Chantal’s lawyer told the Telegraaf his client is delighted that the IP address has been found. ‘We’ve fought for this for a year,’ he said. ‘Now we can move on.’
