Problem description
============================

Spammers signed up for the bulk email service using the victim’s email address. As a result, the victim is being «listbombed» with transactional messages and bulk email campaigns.

Problem resolution
============================

In order to resolve this spam problem (and have this SBL listing removed), the affected sender must take the folloing actions:

a) Implementing CAPTCHA to prevent automated subscriptions
b) Implementing Confirmed Opt In (COI) if not already done so
c) Clean up their email address list (e.g. sending out a permission pass / COI)
