I check my stats every once in awhile to see who's referring to my site. So, here's your PSA for the day - vampire stats is a phishing site. They'll hit your website a dozen times in the hopes you'll then see who they are by clicking the link in your stats page. Don't.
Ditto for r e f e r e r (online there is a '-' between the letters). Just looking for eyeballs on their site, not sending real traffic to you.
Without clicking the link, how can you know this stuff? Google search the site. I found bloggers writing about these sites. You can also read the description of the pages you found. Generally a lot of nonsense.
