I remember, about 12 years ago, when someone pointed this out as one of the big failings; right after a moderator changed the title of a page/site (which was shown live on Channel 4 on a Sunday morning) to "fck fckety fck fck fck".

They were repeatedly told that it wasn't an issue... and didn't really happen in the real world... and that you just needed moderators you could 100% trust.
