Pingback question

In the last two days, I’ve gotten two pingbacks for a post on my blog. I don’t know if it’s legit or spam. I was hoping someone with a little more experience could tell me. The message is included below:

URL : http://bookmarksurl.com/tags/101/200812/process-server-6.html

I didn’t want to accept it or click on the link because I was unsure if it was legit or not. Any feedback would be greatly appreciated.

Thanks!
