I have a friend who purchased a domain name recently that he found out (after buying it) is apparently blocked by many corporate firewalls or proxies b/c it's been tagged as porn by the blacklist db they're using.
Are there any common agencies he can appeal to in order to get the domain name off the black lists?
It's not just one corporation, either, he's looking at marketing a subscription-based service to a certain industry, so any contacting a particular firewall/proxy admin and have them manually update the blacklist won't scale well.
Thanks in advance. Paul
