There is a rule against offensive language, and there is a rule against "naming and shaming."
You can disable chat or block players who offend you, and then report them to chess.com using the "Help & Support" link on the bottom of each chess.com page.
After you click on the Help and Support link, click on "Contact" in the upper right and send support a message about the offense.
But do not talk about the offense in the forums while using the person's name.
{Evidence deleted because of the no naming rule in these forums}
As you can see, this jerk called me gay because I lost and he insulted a large group of people. He should be banned for intolerance.
