"7 ABUSIVE BEHAVIOR - Any verbal abuse or other abuse of a MSCS
official or other competitor may cause disqualification and loss of money
and points for the evening. This rule is for the driver, owner, and/or crew
member.
A second occurrence during the season may result in the team
suspension for the rest of the season with no refund of licenses or fees
already paid."

I have underlined a key word in rule 7 above. Using the word "may" dillutes the rule, and allows flexiblity in enforcement.
