The best way to report a player is to do it directly from the game. The report button can be found in several places.
- Scoreboard. If the player you want to report is in the same COOP or PVP room, tap the Scoreboard button at the bottom of the screen, then tap the + button next to the player's nickname. Select Report to open the reporting form.
- Friends list. If the player is on your friends list, tap their name and tap the Report button above the chat window to open the reporting form.
If you have screenshots or more details that you want to add, just reply to the e-mail you receive after submitting the report form.
