That's what you get for playing our latest forum pest. He's a probable engine user with the ability to antagonise every opponent with his loudmouthed trash talk. Just put him on ignore and make sure you never play him again. His avatar isn't him.
Or you could report him to admin. Enough complaints and he'll get kicked out, hopefully.
Check the game's settings: Explore the game's options or settings menu. Look for any features related to blocking or muting players, or managing in-game communications.
Report the user: Most games have a reporting system in place to address inappropriate behavior. Locate the reporting feature within the game and provide a detailed description of the issue, including any offensive messages you've received.
Contact customer support: If you're unable to find the necessary settings or reporting feature, reach out to the game's customer support team. They should be able to guide you on how to block or mute players, or provide further assistance in dealing with the issue.
In any event, if you cannot find the appropriate option in all the menus, there is always the option to Send Feedback by clicking that link at the bottom of every page.
