Referrer values are passed by web browsers and show how a page was come by. Let’s say you search on Google for websites about a particular subject. If you click on a search result from a to visit a website then the destination website will have an entry in its access logs showing a referral from the originating website, Google. Referrer values can be very useful in applications such as security and are essential to webmasters as they show how their site is being linked to.
From a web access blog that has been spammed, you can see the timestamps of the visits to the site as well as the IP address of the visitor and the referrer value that was passed along with the visitor showing where the visit originated.
The best way to get rid of these trackbacks or comments is to intially “delete” them in your moderation, then in “options” ensure that users must be approved and registered to comment. Finally, as a last resort, in “discussion” to disallow “comments” and “pings” altogether.
