This is the tweet that he is being fined...Mark Cuban tweeted 'Im sorry NBA fans. Ive tried for 13 yrs to fix the officiating in this league and I have failed miserably. Any Suggestions ? I need help' on Jan. 5, 2013. The NBA said that Cuban violated a league policy that prohibits coaches, owners and players from publicly criticizing game officials or the officiating. Since this tweet will cost approx. $1,852 per word, it is one of the most expensive non-advertising tweets in history.
