Need help with finding domain owner ASAP

Hi guys, I really need to find a domain owner.

I put up an ad renting a home about an year ago but deleted that ad after the house was rented. The problem is most probably he scraped the ad and put it up on his site.

I tried contacting him but cannot find any information on his Contact page and don't know how to see his email or phone number to ask him to delete the ad.

I would really appreciate if anyone could help me take off the ad or get in contact with the website owner.

Thanks
