The 0Spam primary source of support comes in the form of donations to the project by the IT & sysadmin community. Each donation helps us improve the platform and add additional functionality improving spam detection and false positive awareness.

The Project also offers additional services, including:

• IP Notification Services: Network Administrators are notified each time an IP that they manage is listed in the 0spam database. Confirmed network administrators are granted a 24 hour grace period before listings go live. However, repeated abuse of this feature will result in permanant rejection from the IP Notifiation services.
• Donations from IP owners: Currently we provide free notifications to IP owner Abuse Contacts.
  You must be the official IP abuse contact in order to receive these notifications.
