Theresa,
 
Thanks for outlining your "disciplinary process". It's completely in line with what I have been proposing and/or doing for the two years I have acted as a steward of Wikipedia.

The idea is to begin by assuming good faith. Explain, request, remind.
 
If that doesn't work, start turning on the heat. Warn, temp block, ban.
 
It's amazing how many variations of this principle have appeared over the nearly 3 years Wikipedia has been in operation.
