Please remember: Good candidates for this category are sites on Usenet server software. For Usenet access providers the right category is Computers/Usenet/Feed Services.
Software for news servers which filters news, either to cut down spam, or handle other forms of third-party tagging or removal system.
Any Usenet antispam software or plug-in on the server side is more than welcome here, but if the proposal is about e-mail, blogs or web forums, then this category is not the right place. Keep in mind that a submission in the wrong category would delay its review a lot.
