Abused / misconfigured newsletter service (listbombing)

The host at this IP address (209.85.222.194) is emitting bulk email to unconfirmed email addresses. The newsletter service associated with this IP address is not properly configured and hence being abused by spammers and malicious actors to «listbomb» innocent internet users.

Problem description
============================
The newsletter service (Freya MARTIN <freya.martin@expolists.com>) is using the referenced IP address to send bulk email. Unfortunately, the said newsletter service is not verifying the email address of new subscribers. Due to this, the service can be easily be abused to «listbomb» internet users.

Problem resolution
============================
The newsletter service needs to clean up their email address list and ensure that bulk emails are only being sent to recipients who have verifiably subscribed to their bulk email service.

In addition, the newsletter service should take appropriate actions to prevent further abuse of their service:

a) Implementing CAPTCHA to prevent automated subscriptions
b) Implementing Confirmed Opt In (COI) to prevent that abusers can add random email addresses to the newsletter service that are not owned by the subscriber
c) Read the documentation below
