Need Help Tracking Down a Scumbag

After having 2-3 random friend requests everyday for the past week beginning with strange questions like, "How did you get so many games?" and usually ending with begging, I finally figured out where all of these bottom feeders are coming from.

Apparently, unbeknownst to me, my Steam username and avatar are being used on somebody's website for attracting Prize Rebel referrals. Not only is this person using my identity without permission (as one of his happy customers) but he also has a fake quote on his site too which he represents as coming from my lips.

I have no knowledge of who this guy is, I never have had dealings with Prize Rebel, and I most certainly did not give him a quote for his website. His website is http://freesteamgifts.webs.com/.

Now the issue is, how to find out who is responsible for this and have it stopped. I've tried using a whois search on a few different domain registration and lookup sites, but they tend to either return errors or give me the data on the domain which is hosting his free site. I have also contacted Prize Rebel just now, insisting his account there be deactivated (hopefully removing his reason for having the site in the first place) or else I will explore legal options against him and Prize Rebel.

I will contact the domain providing the free site (webs.com) if necessary, but, their complaint form requires a phone number and presumably that is how they will contact me. I much prefer handle my business by email.

If anyone knows of an alternate way of figuring out who is running this domain, or if you personally just happen to know, please let me know so I can get in contact with this scumbag.

Update:

Carefully watching his youtube videos has led me to identify this as one of his accounts.

Update 2:

Sometime this morning Webs.com was good enough to take down the offending website. I have still not heard back from Prize Rebel or from the individual (I tried contacting him by a few different methods). That all is a bit moot now (though it would of course be a bit satisfying to know his referral account was frozen as well), but I am happy with the outcome.

Thank you to everybody who has provided suggestions, information, and/or support.
