I've administered multiple boards with thousands of members. Forum software having a field for notes about users is normal for administrative purposes. As an example: If you have a new user who you have issues with then restore to normal status, you'd make a note in case the person has an issue later.
I respect and like Ovah, but am surprised he would have ever publicly questioned @cheryl about something like that, especially since he used to be a mod. This type of thing should have been a PM.
Lastly this is a completely different forum software than existed here 8 years ago so this is a moot point.
