If its free, how do you make money to support the project?

The 0Spam primary source of support comes in the form of donations to the project. 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: $100/IP or $500/IP Block[max Class-C] (One Time Fee)
This Service allows Network Administrators to be 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.
IP Management Access: (currently free and available to IP Abuse Contacts only)
You must be the official IP abuse contact in order to use this service which is currently in beta. The service allows you to see the current status for all IP's within your control in one easy to see menu.
