Please note that SURBL is not a feedback loop or deliverability service and does not support listwashing. If you need help finding an abusive affiliate or sender, some of the references below may help. In addition, using confirmed opt in generally reduces abuse to near zero since it proves that the owner of the mailbox actually gives permission to be mailed. Without confirmed opt in there is no direct proof of that permission.
You have been listed for a long time so a good start would be to monitor services like us for listings. And also check your logfiles and SPF/DKIM as its stunning this could happen for such a long time and without beeing noticed by your administrators.
If the site appears in any outbound messages, please be sure that best practices are followed. In particular, we and many others urge that all subscriptions be closed-loop confirmed as described in some of the references below.
