A lightweight, must-have plugin with great support
by Benjamin·2 months ago

Antispam for Contact Form 7 offers a lot of options to tweak, making it easy to fine-tune the protection based on the type and volume of traffic your website receives. It works reliably and has significantly reduced spam submissions without causing issues for legitimate users.

Erik has been great at handling support through the WordPress forums: quick, helpful, and knowledgeable. That level of support makes an already great plugin even better.

Broken plugin
by lemurnick·4 months ago·17 replies

Someone got their hands dirty and broke the plugin. After the update, the field data was inaccessible, and it started banning everyone. And rightly so—the bad plugin should be removed. Long live it – $spam = true; $reason[‘no_ip’] = ‘Address field empty’;

IP address field of $remote_ip is empty, this means it has been modified, removed or hacked! (i’m getting the real ip from http header). Broken plugin – solution to remove!

Great plugin
by o2xav·4 months ago·2 replies

A great plugin that requires a little thinking and configuration, but once setup properly it’s awesome.

The latest version makes it even better. Good job !

Blocked everything for non-logged-in users.
by Degas·1 year ago·1 reply

We’ve just found that whilst the plugin was stopping spam sucessfully, it also blocked all submissions from non-logged-in users (‘There was an error trying to end your request. Please try again later’). Recommend checking this first in case of any potential conflicts.
