What is referrer spam?

My name is Eugene Baker and I'm a product director at a start up company called SohoOs ( http://www.sohoos.com ). I know I'm not supposed to do any promotions here, so I want. What I really do need is people to test out the new system and tell me what additional features need to be implemented. It's completely free so go on and take a crack at it. Basically, it's business management software that's free.

Tell me what you think people, I'll owe you a cup of coffee!

Good day,
Referrer spam is when a spammer sends fake referrers to your server. They do this because they know most web stats lists referrers as hyperlinks. They then submit your stats to the search engines in the hopes that they will crawl your stats and find that link. They also hope you click on that link yourself.
