I'd like to know if anyone has seen an add-on (or a good way to do it natively) which would allow moderators to basically monitor users. Sometimes users are suspected of something that you can't quite deal with until you notice a pattern. It's in no way convenient to constantly check activity of people who might only login once a month, so this combined with alerts would be very helpful. In my head I see it as a sort of a single, universal follow list moderators to share. Thoughts?
