Top Comments is a simple, easy to setup and manage comments rating plugin. It adds the current score and the voting button at the end of each comment. Also displays the score in the comments RSS feed and in the admin area.
The plugin uses AJAX to process the votes and has several methods to prevent cheating (multiple consecutive votes). It also can display the top rated comments in the sidebar by using template tag or widget.
Uses the JavaScript anti-bot checks from <a href="https://wordpress.org/extend/plugins/wp-hashcash/" rel="ugc">WP-Hashcash</a> by <a href="https://wordpress.org/extend/plugins/profile/ecb29" rel="ugc">ecb29</a> and <a href="https://wordpress.org/extend/plugins/profile/donncha" rel="ugc">donncha</a>.

I hope you enjoy this plugin!  If you have any questions, please post a topic in the for support forum.

Couldn't believe there was nothing out there like this!

Although I wish it had some options for placement. Not sure I like it above the author avatar.

Pretty cool

Let visitors vote up and down on bbPress topics and replies just like Reddit or Stack Overflow!
