Someone is griefing, cheating, or breaking the rules. Here is the proper way to file a report that actually gets action.

The fastest method is the in-game client. Click on the player username and select Report user. This sends the report directly to the moderation system where it gets tracked and correlated with other reports against the same player.
You can also navigate to the BAR battle server website, find the relevant match, click the players tab, and report the user from there. This works well if you already left the game and need to report someone after the match ended.
If the issue involves Discord behavior rather than gameplay, the community runs a ticket bot for private moderation contact. Use the ticket channel to open a private report. The moderation team will handle it separately from in-game reports.
Keep in-game reports within the game reporting system. That makes it possible to track patterns across multiple reports and take appropriate action.
