Wordpress Spam Blocker
WP (Wordpress) Spam Blocker blocks comment spam by using a combination of time-based hash (a.k.a. Time Based Tokens, TBT) and JavaScript (AJAX). When a comment is posted the plugin validates a hash based on time (and some other parameters). Comments posted via automated means will not have a hash or will have an expired hash and will be rejected. Unlike using a captcha, this does not place any burden on the commenter. Are you tired of logging into your wp admin to see it loaded with comment spam and have to delete it? This takes up plenty of time that you can save by using Wordpress Spam Blocker.
Additionally, WP Spam Blocker uses ajax to get the hash only when the form is submitted instead of adding it statically to the page (which is cached by caching plugins). This adds another layer of security and makes it compatible with caching plugins like WP-Cache.
Wp Spam Blocker Features:
1. Blocks automated comment spam and ensures that your commenters are human.
2. Works without inconveniencing visitors with CAPTCHAs, challenge questions, etc.
3. The plugin requires no database access and adds almost zero overhead.
4. The plugin works out of the box without any configuration or setup.
5. Compatible with all cache plugins, including WP-Cache.
6. No Editing Of Php Files Required.
Installation: Download the .zip file and upload the file ‘captcha-free.php’ to your ‘/wp-content/plugins’ directory. Now login to the Wordpress administration area and activate it under the “Plugins” section. That’s it! WP Spam Blocker will start blocking comment spam behind the scenes.
I use Wp-Spamfree and that does a great job. How is this plugin better? A comparison would be nice.
What happens with pingbacks and trackbacks?
HOW? What about using it with Brian’s Threaded comments or comment pagination?
Just thought I’d ask. I’ll test it on my own blogs too against these other plugins and let you know.
Are you using this plugin on this page? I’m filling out this comment to test it…
Thanks!

i tried it on my site and so far so good. zero spams!
I have used this technique on various websites for years to avoid automated submissions and reloads, I was always wondering why no one implements this technique for spam blocking. Your idea to use AJAX is great, let me take a deeper look into your code. Thanks anyway
Hello? I think the plugin doesn’t accept trackbacks and pingbacks. Any ideas?
