Jason,  There's unfortunately no way to prevent a listable tag that no longer points to an object from appearing.   Raj
What should happen to listable tags when there are no longer objects using them?  I have some listable tags that are returned by getlistabletags() that have no objects returned when I query for the tag using listObjects().  These tags were previously in use, but the objects that were using them have since been deleted.  How do I get listable tags to stop appearing in getlistabletags() when they are no longer in use?
