Some people really like that WordPress sends pings from your own site to your own site when you write posts; it gives them a trail of related posts.
Some people do not like this behavior; it clutters up their comments.
This plugin disables intra-blog pinging.
Once activated, there’s nothing for you to do. However, head to Settings -> Discussion and you’ll find a field in which you can, if you wish, specify more domains that won’t be pinged. Why? Well, maybe you often refer to other sites that you maintain or, particularly, you run a multi-site and don’t want each blog pinging the other – specify a list here and you’re sorted.

TalkBack is a open-source secure LinkBack mechanism based on a public-key cryptography that aims at tackling the blog spam problem at its root: instead of detecting spam via the content analysis like Akismet, TalkBack prevents spammers from posting LinkBack notifications. When installed TalkbBack add the two following lines of defense to your blog:
<ul>
<li>
The first line of defense is a lightweight PKI (Public Key Infrastructure) that ensures the identity of blogs by using public key cryptography. Moreover using cryptography allows TalkBack to guarantee that no one can tampers with your TalkBack notifications and that the receiver will received them unaltered.
</li>
<li>
The second line of defense, is a global rate limiting system enforced by the TalkBack authorities that ensures that with a single blog identity, a spammer cannot massively spam TalkBack aware blogs.
</li>
</ul>
TalkBack is compatible with every other defense mechanism and do not store/disclose any private information about your blog or you. As a matter of fact if you don’t trust the network, TalkBack can also encrypt your notification to protect them from eavesdroppers.
A complete description of Talkback is available here: http://code.google.com/p/talkback-client/downloads/detail?name=talkback-paper.pdf and the source code here: http://code.google.com/p/talkback-client/downloads/detail?name=talkback-wordpress-plugin.pdf
