Stops orders from customers on your block list, such as repeat chargeback offenders, matched by email address, email domain or phone number.

Code
$wpide_block_list = array(
'emails' => array( '[email protected]' ), // Full email addresses.
'domains' => array( 'bad-domain.example' ), // Email domains.
'phones' => array( '+44 7700 900123' ), // Phone numbers.
);
add_action( 'woocommerce_after_checkout_validation', function ( $data, $errors ) use ( $wpide_block_list ) {
$email = strtolower( trim( (string) ( $data['billing_email'] ?? '' ) ) );
$domain = false !== strpos( $email, '@' ) ? substr( strrchr( $email, '@' ), 1 ) : '';
$phone = preg_replace( '/\D/', '', (string) ( $data['billing_phone'] ?? '' ) );
$phones = array_map( function ( $number ) {
return preg_replace( '/\D/', '', $number );
}, $wpide_block_list['phones'] );
$blocked = in_array( $email, array_map( 'strtolower', $wpide_block_list['emails'] ), true )
|| ( $domain && in_array( $domain, array_map( 'strtolower', $wpide_block_list['domains'] ), true ) )
|| ( strlen( $phone ) > 5 && in_array( $phone, $phones, true ) );
if ( $blocked ) {
$errors->add( 'validation', 'Sorry, we are unable to process this order. Please contact us for help.' );
}
}, 10, 2 );Notes
Phone numbers are compared by digits only, and the message is deliberately neutral so blocked customers are not told why.
