My understanding is that the sound (if it's kinda like a squeak) is from lubricant or rubber seal getting rubbed off on the clutch pedal assembly or something - it shouldn't be the throw out bearing.
Pretty sure this is covered somewhere on the forum, and I think the member fixed it by applying grease to the fork or something like that. A design flaw, but not one which should cause mechanical issues. Mine had this at 72,000km, and I don't ride the clutch or do any silly things with it.
EDIT: Here you go
