Kennesaw Mountain Landis, ruled this way:
"Regardless of the verdict of the juries, no player that throws a ball game; no player that undertakes or promises to throw a ball game; 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. . . regardless of the verdict of the juries, baseball is entirely competent to protect itself against crooks, both inside and outside the game."
Seems as if the ban was from playing. This is what I found anyway. Maybe there is more to the ruling.
