Username policy - lichess-org/lila GitHub Wiki

If a username is deemed inappropriate, the user account should be closed.

Usernames are public and displayed all over the site. They will be read by kids using lichess.

In general, a username chosen with the intent of generating negative emotional reactions, is bad. This includes, but is not limited to:

• Usernames with offensive/sensitive topics, e.g. race, gender, sexuality, politics
• Usernames that are disparaging towards others
• Usernames impersonating living people (impersonating means that you can reasonably be mistaken for someone you are not)
• Usernames should not imply you have a FIDE title or the Lichess Master title (LameName.scala)

Moderators will always be able to use their judgment to override these rules. The Terms of Service for Lichess can be found here.
