Blog Spam Blocklist

The BSB is a database of IP addresses that have sent "comment spam".

You can use it for example to mark submitted comments and trackbacks for review.

Lookup an IP

IP or domain:

(lookup this IP)

API

To add BSB lookups to your weblog software, make it lookup [reversed IP].bsb.empty.us. For example to lookup if 10.1.2.3 is in the database do a DNS request for 3.2.1.10.bsb.empty.us. Entries in the database will return an A record of 127.0.0.2.

The domain lookups are in the same domain, so to lookup example.com, lookup example.com.bsb.empty.us. Or if the comment you get includes the url http://poker.example.com/poker.html then check for the existence of poker.example.com.bsb.empty.us.

Note to implementors

If your weblog software blocks/discards the comment rather than just sending it to moderation or some such, please tell the user that on the weblog site rather than redirecting them directly to BSB.
