I've just saw a moderator give a "link only" answer to a post. According to what I know, those type of answers should be avoided.
And then I wondered. Is there any chance that this moderator will handle the flag if I will add one?
Moderarors are trusted with all flags.
Normally we defer handling to someone else at the first hint of a conflict of interest. Generally I don't even touch flags on answers that are competing with mine in the interest of impartiality.
