bwnbwn -- I think he's talking about referral spam. They fetch your page three times in a row about a tenth of a second apart. If you try to go to the referring page, you get re-directed somewhere else. A lot of people have tried to stop it by blocking referrals from .ru, .pl, .ua, .ro. etc, but lately they've switched to .edu and .org using domain names made out of non-English words.
