This plugin adds a stylesheet or image to your blog’s html source code. When a browser loads that stylesheet or image a cookie is dropped. If that user then leaves a comment the cookie is checked. If it doesn’t exist the comment is marked as spam. The plugin can also check how long it took a user to enter a comment. If it’s too fast it’s probably a spam bot. How fast can a legitimate user enter their name, email, web address and enter a well thought out comment?

Great plugin! The most effective to avoid spam since years

By Annonnimmo on August 9, 2021

(REVIEW UPDATED August 2021) Based on my long experience, I think this the simplest, fastest e most effective plugin to avoid spam in WordPress comments. I'm using this plugin on several sites, since years, and it works like a charm. Also on a big website with thousands of daily views (using .htaccess) P.s. It works very well with all versions of WP 5.x

Must have, if you don't use any other spam filters!

If you don't use any other spam filter plugins, then you can rely on this to stop spam comments for sure!

There used to be 2 types of anti-spam plugins. The first one will block all comments, and also block shopping carts if you run a site where people need to pay. The second doesn't work. There is now a 3rd category, and this one not only works, but also will not block shopping carts. This anti-spam works well with Clickbank and WP eMember possibly other carts as well.

Thank you so much! The last update stopped the anti-spam from Tips and Tricks HQ with their WP Security plugin, and I was inundated with 100s of spam comments per day. Now, this solution works, and everything is sent to spam, without messing with my shopping cart.

Thank you so much.

very easy and no more spam!

I'd been getting a dozen spams a day on two of my sites. We installed "Stop Spam Comments" on one and "Cookies for Comments" on the other. Both worked perfectly. No more spam. Thanks!
