[GEEK] Site Referral Log Mystery: How does this happen?

Can someone explain why my referrer log for this site is full of spamish- looking like urls, none of which actually have a link to it? For example: texasholdemcenteral.com, www.freewebs.com, skate.cyberfreehost.com, google.co.uk/search, www.myspace.com/nyjeter2ox, images.google.ca/imgres, images.google.co.uk/imgres, evilplots.com/texas-holdem, www.texasholdemcenteral.com, online-casino.blest-casino.com/ , www.favorite- casino.com/online-casino, www.sportscribe.com/poker-party, com/texas- holdem.html, favorite-casino.com/casino. And so on? It's got to have something to do with page rank and Google, but I would love to understand HOW and WHY they do it. Technorati Tags: Geeky, google
