All great points Alexandra,
When topics get out of control and tempers need to be cooled, those involved are sent PM's warning that their behavior is not appropriate, or something similar. It is also addressed publicly to show the membership that this type of behavior is not accepted and that everyone can see that. It is not done to single anyone out and it is usually short and sweet like "Just to let you know that you are getting close", or "Cool it folks", "Step back and take a breath".
Personal information should not be posted in the forums but in the members profile where is is safe from the scrutiny of the web harvesters, and lets say unsavory characters that roam the web. Remember guests have free access to view the forums. Personal information that is usually deleted is an apparent teen advertising their age and email address, or a member advertising their email address, in which case the email address is deleted and replaced with something like "You can contact me using the email address found in my profile".
Basically speaking moderators are required to ensure that the rules are followed which in turn goes a long way in keeping Susan's a safe haven for her members. I would just like to add that the rules apply to us all from the top down, and that Susan has the final word.
