This is a bit sad.
Megamoon24 was sarcastic above, I think (I hope).
If you simply click on the Original Poster's name, as Meeplelowda said... it will lead you to his/her profile.
There, you will see at the top, next to the username (between brackets), the username that was moderated.
It had a 3-letter F word in it, that in general is used as a slang (from early 20th. century) (but originally, in UK, it meant cigarette - from late 19th. century, like RicardoRix mentioned).
Same as a certain 3-letter G word that originally meant happy, but then got a similar meaning (like f**, but less offensive).
Lilyash means nothing, and it's neither the OP's current username that was chosen as a result of the moderation (SongTitleLil), nor the username that was moderated (F**AshLil). I think Megamoon24 was joking.
Anyway, the moderation is perhaps ok, simply because of how common this offensive slang is, despite the initial meaning of the word.
But on the other hand, I think RicardoRix is right - saying F** followed by Ash should be more obvious that the F word is used as cigarette, rather than the more common slang meaning.
