Zero Spam for WordPress

Has been my go-to anti-spam plugin for quite some time. I've used many of the techniques individually on many sites. Having them rolled up into a single plugin is just amazing!

All 1-star reviews that say it doesn't work, don't have it setup/integrated properly, which can take a little bit of effort. There is no magical anti-spam protection that instantly happens when you activate it. BUT, once you do implement a few of the techniques this plugin provides, spam becomes a thing of the past.  

Prior to v5.2.15, would have been an easy 5-star rating. Because of v5.2.15, I regrettably have to give it 1-star review. Plugin author: This is an ANTI-SPAM plugin, NOT a Ukraine support plugin. If you want to show your support for Ukraine, make a plugin for it. DON'T ruin a useful plugin by injecting unrelated political beliefs it into it. Blocking spam is blocking spam. Supporting Ukraine is supporting Ukraine. Mix them together and you just end up ruining both.

v5.2.15
    feat(ukraine): we’ll no longer provide protection for .ru, .su, and .by domains & will display a banner of support for the ukrainian people on those sites – united with ukraine

Personal Note to the Plugin Author:
It's your plugin, you can do what you want, but here's an important question: Is this plugin for YOU (the plugin author) to broadcast political beliefs, or for US (the plugin users) to block spam? Between those two, which one is more important? Pick one and go with it. If you pick personal political beliefs over plugin user functionality then it's only a matter of time until someone takes all of your hard work on this plugin, removes your political beliefs, releases it as a new plugin, and surpasses you in # of installs, making this plugin obsolete. You will be your own undoing. Would hate to see that happen to an otherwise WONDERFUL & AMAZING plugin!

Remove personal politics from this plugin, and my review will change to the 5-star review that it deserves.

Politics Ruin Yet Another Good Thing


I am using this plugin on all of my sites and it is really helpful in reducing spam. It has a very broad range of functionality and integrates well. This plugin also has good support. Great work


Very useful plugin


It's an obvois pay to use plugin with a direkt URL to the License Key website, which is basically prohibited by wordpress.org. It's even very intrusive with its payment demand. Since I have installed these type of plugins, I have more spam than before.


Pay to use

No spam, no scams, just seamless experiences with Zero Spam for WordPress - the shield your site deserves.
