I got another response, again in fairly short order, indicating that this is exactly what they have done. He also gave me a phone number to call if I should ever notice their spider visiting our web sites again in the future. So they are responsive to requests to be put on their "don't scan me" list. That doesn't change the fact that their scanning methods are on the harsh side, but at least you can get them to stop scanning your network without adding another firewall rule.
