I discovered a new tab in my user profile.
Very useful. I have always wished such an overview so that it can help me to trackback my downvotes so that I can if necessary undo them.
But I was wondering, can moderators see them for each other user?
No, moderators cannot see this information. Waffles confirms this in a comment here:
no ... mods can not see it
For privacy reasons, you can only see it for your own account.
