Blocking Usenet spam

How you block Usenet spam depends on what news server software you use. If you use INN version 1.4unoff2 or higher, you can block news spam very simply. Just add the name of a spamming site to the ME line in your newsfeeds file. For example:
ME/badsite.com [...etc...]

If you run earlier version of INN, you can get a patch to support this here.

Tsuneo Tanaka has contributed another patch to INN 1.4unoff4 that performs very flexible filtering of the news stream. This patch is very likely not appropriate for full feed sites, but would be useful for leaf sites with a partial feed.

If you run C News or another news server, you will have to get your feed sites to block the spam for you. This time, the entry is added on their side in the newsfeeds or sys file. For example:

spamhater/badsite.com [...etc...]

If you use commercially supported news software, request your vendor to provide local blocking as an enhancement.

The NoCeM Protocol is a useful tool for controlling spam in your news spool.
