If you have a consistent offender who fraudulently donates using the same email address over and over, support can blacklist the email address and/or IP address using this setting. Contact Luminate support and provide the email addresses and/or IP addresses.

Note: We cannot blacklist IPs and email addresses for carding runs. Carding runs are typically conducted by an automated script that frequently changes their email and IP. This method of blocking would not be effective. To combat carding runs, you can use Luminate's fraud settings. Luminate Online's Velocity Fraud Control - Fraud Prevention Settings
