Sounds like referral spammers. They fake referrals to your site in order to show up in your stats. If you're wondering how that would help - consider this thread as an example. You've effectively created some links for them by linking to your stats. Lots of sites have their stats pages open to the public and search engines, hence the benefit.

I don't think you can prevent it happening, except perhaps by banning individual sites or IP addresses (not that practical). The main thing is to make sure they don't get any benefit - keep your stats hidden from search engines.
