Simple Trackback Validation Plugin performs a simple but very effective test on all incoming trackbacks in order to stop trackback spam. Now with topsy.com blocker.
How it works:
When a trackback is received, this plugin
<ol>
<li>
checks for topsy.com trackbacks and marks this as spam.
</li>
<li>
checks if the IP address of the trackback sender is equal to the IP address of the webserver the trackback URL is referring to. This reveals almost every spam trackback (more than 99%) since spammers do usually use bots which are not running on the machine of their customers.
</li>
<li>
retrieves the web page located at the URL included in the trackback. If the page doesn’t a link to your blog, the trackback is considered to be spam. Since most trackback spammers do not set up custom web pages linking to the blogs they attack, this simple test will quickly reveal illegitimate trackbacks. Also, bloggers can be stopped abusing trackback by sending trackbacks with their blog software or webservices without having a link to the post.
</li>
</ol>
There are several options available and you also can enable logging to get all actions, which are performed by the plugin, logged. Also, you can select how to treat spam trackbacks (do not save in the database or mark as spam or place into moderation) and several other stuff.

When you link to a website you can send it a Webmention to notify it and then that website may display your post as a comment, like, or other response, and presto, you’re having a conversation from one site to another!
A <a href="https://www.w3.org/TR/webmention/" rel="nofollow ugc">Webmention</a> is a notification that one URL links to another. Sending a Webmention is not limited to blog posts, and can be used for additional kinds of content and responses as well.
For example, a response can be an RSVP to an event, an indication that someone “likes” another post, a “bookmark” of another post, and many others. Webmention enables these interactions to happen across different websites, enabling a distributed social web.
The Webmention plugin supports the Webmention protocol, giving you support for sending and receiving Webmentions. It offers a simple built in presentation.

Webmention

Easiest way to integrate Webmentions!

This is fantastic. I joined indieweb a few days ago. Last night I wanted to know "So what actually does the technical implementation of a WebMention look like?". I am now working on improving my understanding and perhaps I'll create some documentation that I find easier than the w3c spec or a WP plugin.

Great work, very patient team.

Wonderful

A good plugin that does something very useful. Love the indieweb and Matthias Pfeferle does such great work
