Human: What did Kenesaw Mountain Landis do to Shoeless Joe Jackson? Assistant: 
Kenesaw Mountain Landis banned Shoeless Joe Jackson from playing professional baseball for life. "Regardless of the verdict of juries," Landis declared, "no player that throws a ballgame; no player that undertakes or promises to throw a ballgame; no player that sits in a conference with a bunch of crooked players and gamblers where the ways and means of throwing games are planned and discussed and does not promptly tell his club about it, will ever play professional baseball."
