Here's an idea...
In the AntiPoints popup, add clickline to add your username to the comment/assignment of the Points, BUT DON'T MAKE IT A NECESSITY TO SEND IT . Then show that percentage in the 'User tends to assign' area of each post. This would encourage users to 'sign off' on every AntiPoint assignment, and not just sign off on the Positive ones. (Thinking...if the percentage of neg. points match the percentage of neg. points the user 'tends to apply'...see where I'm going with this?...) For instance...(User tends to assign 75% positive, 25% negative), and just below that (User tends to assign x% signed and x% unsigned)
May be playing on the guilt factor, but it would encourage users to take responsiblity for all 'Points' assigned, and along with the 'contact user' addition, could finally take the abusers out of the equation.
Just an idea...
