Why are comments on Yahoo news that contain the word Talmud instantly deleted?

An Iranian poster brought this to my attention. I'd like to know why Yahoo is censoring comments containing the word Talmud, and if there are other words that are treated similarly?
Update: I'm not making this up. I just picked a random news story and left a comment that contained only the word Talmud, then refreshed the screen. The comment never showed up. I tried it twice.
I should mention that I'm posting from the US.
