The blacklist setting prevents the patron from completing online orders. Once blacklisted, the account can no longer finish online transactions. Any subsequent accounts the patron creates during checkout will inherit the blacklist status. Already purchased tickets will display a 'Check ID' message when scanned.
To enable the setting go to CRM > CUSTOMER DETAILS and then locate the user you want to blacklist. Next, click the edit pencil at the top of their profile, click the blacklist setting and press SAVE.

If the patron already has tickets, a CHECK ID message when the ticket is scanned.

Note: We can not block a credit card from being used. The blacklisted patron can also still checkout as a guest if you have "checkout as guest" enabled. However, if checkout as guest was used and the email address was blacklisted, the order would be linked to the blacklisted email address and the scan message would show up when the ticket is scanned at the door.
All orders on the users account will show Req ID Check (require ID check).
