Yes, there are people NOT living in this decade!!
Isn't there a time limit on the UserReference?

Using User Keys
To associate a user variable with a particular user, Tango must have a piece of
information that it can use to uniquely identify that user.
Tango refers to the unique identifier used for tracking a user's variables as the
user key (formerly known as the global key). Tango has several settings allowing you
to control what information is used as the user key. Tango default behavior is to use
three meta tags as the value of userKey:
<@APPKEY><@USERREFERENCE><@CGIPARAM CLIENT_IP>
These parts of the userKey function as follows:
<@APPKEY> returns the key value of the current application
scope. This ensures that users in different applications cannot share variables.
<@USERREFERENCE> generates a unique number for tracking each
user.
<@CGIPARAM CLIENT_IP> returns the IP address of the user who is
accessing a particular Tango application file. This ensures that a session can not be
taken over by someone from another IP address.
