I've been removed from a Fantasy Sport's league or group
Commissioners of private leagues have complete authority over their league or group. They have the power to remove anyone they'd like for any reason at any time.
If you've been removed by your Commissioner, Yahoo will email you to let you know and provide you with the Commissioner's email address.
Yahoo Sports doesn't intervene in private league matters. If you have any questions or concerns, you'll need to contact the Commissioner at the email address you're provided.
