I have been looking through my hosts logs of late and I have noticed an ever increasing amount of referrer spam. Now whilst this is of no real concern to me as I do not use referrer logs or display them anywhere it is however really quite annoying to see this type of thing in your logs.

Apparently its not a new scam even though I have only started see it from the beginning of this year.

Those of you using referrers from the server logs to generate link lists on your websites should take note of the fixes available.

A Referrer is the url some one was on when they found a link to your site. Servers like Apache will log these urls along with users activity. This allows you to see what sites are linking to you and providing you with traffic.
