Help at and away from the table.

Guest play does not require an email address. A permanent account lets you keep progress and appear on the leaderboard. Use Forgot password? on the sign-in screen if you lose access. Account deletion is available inside Privacy & Account and removes the associated profile and gameplay data.
In a lobby, tap the menu beside a player's name. During a match, tap the shield button. Reports are reviewed for inappropriate usernames, harassment, disruptive play or cheating. Blocking prevents the two accounts from being placed at the same private or ranked table in the future. The current match continues so blocking cannot be used to avoid a ranked result.
These are summarised from the Terms of Use, which every player accepts before playing. Reports are reviewed and acted on as promptly as reasonably possible. If your account has been suspended and you believe it was a mistake, email support with your username.
