Using Jamroom
Update the jrComments module to the latest 2.4.3. That will not inform owners that they have a comment if they can not go to the location of the comment and see the new comment.
It might pay to use the LOG OFF button in the USER ONLINE tab of the dashboard to log that user out if your users are continuously logged in. That will make sure the 'profile_active' key matches what its set to. Might not be needed but if the emails still go out after this update then do that.
