security

Hi everyone,

I'm still pretty new to web development, and have a question about security.

Every day I look at the "Latest Visitors" in my CPanel, and today there were some strange entries (one is pasted below).

Not knowing any better, it looks to me like there is some site that's referring users to my site, for some reason. Can someone explain what these really are, and if it's something to be concerned about? Thanks!
