The free version has options that in some others are paid, that I loved. Easy to use, very intuitive. But to be honest the paid version has no comparison, it is very good. It is a very affordable price.
I really appreciate all the pre-set options and the ability to customize them. Thanks for this plugin for many years. I'm glad it's got new life from being adopted by a new plugin owner. Looking forward to its continued development.
I like the fact this plugin uses multiple sources of repudible spam blacklists. This provides redundancy instead of only relying on one, like so many other competitors. Suggestion: I would like to be able to input the URL of a custom IP block list and have this plugin block those IPs as well. The plugin should update or ping this IP block list for any changes and apply them.
Solving the age-old problem of comment spam that has plagued every WordPress developer since the dawn of time. These parasitic track backs and authority suckers are pervasive and disgusting. This lightweight little plugin is one of the first I activate on any site I create. Why pay $50 every month to protect your sites? This is a very budget friendly premium plugin at $50 for unlimited. It's a no brainer.
I was having the absolute worst time with spam registrations. Literally every day I'd have about 400+ spam registrations that I'd have to manually clean-out per day. After a while, I knew I wouldn't be able to continue like this. I searched the WordPress Plugin Repository for a plugin which would alleviate these issues and I decided to try it out. With the various control options, it quickly became apparent that this was the plugin that I've been needing. I haven't had any issues since installing the plugin.
