While it probably is just a mistake on Tolkien's part the idea of an elvish graffiti sprayer are hilarious to imagine.

Galadriel: Celeborn....

C: Yes, dear?

G: Would you care to explain why my Mirror just showed you and Haldir carving Moria into the dwarves doors?

C: Oh, that. Well, you see it is a warning to anybody who enters that there is a balrog in there.

Cue Galadriel throwing Celeborn out of the talan for the night.
