WTF?

I've been receiving strange LJ-comments for a while. For "strange" I mean anonymous comments commented on the same entry and said nothing except "good job admin, keep it up". I mean, I'm thankful that somebody read my entry and commented and it's positive, but ALL for them anonymous and about two per day? And sometimes with a headline of "Paris Hilton"? WTF?

The entry that is getting crowd:

Does anybody know what's going on?
