So here's where you can sign up and get your very own API key, which is required to add spammers to our databse. All of these fields are required, and you can be confident your email address will be kept completely private (it's only used to email the key to you once it's generated). Including your website where your forum is located is required too, and also kept private.
If, in the future I decide to make a list of sites that contribute, I will ask your permission to link to your site via email.
