Someone is submitting around 20-30 of the exact same links to my directory!

It is a crappy money making click through website that is constantly being submitted, and so I decided to add a value to db_referrers to stop them submitting from another URL.

Do I add db_referrers = (audio-grabber.com,www.audio-grabber.com)

or db_referrers = ('audio-grabber.com','www.audio-grabber.com')

Thanks
