Poker hits?

Buncha spam in my referrers, thoughts or explanations welcome.

I run a small community site (nuked) and I've noticed over time when looking at my referrals in my site stats that I have a tons of these listed:

Links from an external page (other web sites except search engines):

http://www.example.com
<snip>

and on and on and on

There is no content from these on the site. The site has nothing to do with these. I understand that it's a bot and spam of some sort but I'm not sure if I should worry about it or just ignore them or whatever.

The thing is that there are so many of them I'm sure it's sucking down server cycles if they're actually on the site crawling and it sure makes it a read to figure out real external links from bogus ones.

I'm also sure that I'm not the only one but searching on this site didn't bring me what I sought and google just brought up a buncha crap (I might as well have typed 'porn' for my search query).

So any light you could have or suggestions for me would be greatly appreciated!

Thanks

I deny access to this sort of spam using php but I still find them in the logs and serve 0 length files as they don't care about the content or use HEAD requests.

thanks for your reply. That's definately a start. Could you point me to anywhere I might learn more about blocking this sort of thing?

Thx!

Depending on your server, .htaccess, scripting language you can find articles by using the search facility, for example :
[google.com...]
