Tracking specific users


Active member
I have a user that I am concerned may become a troll and I'd like to receive alerts anytime he makes a post but I'd prefer for him to not have any indications that I'm doing so.

I've seen add-ons that will do this for users that you are following, but haven't been able to locate anything that will allow an admin to do this without being a follower of the user.

So, is there an add-on that will allow me get alerts for a specific user without being a follow of that user?
