Thank you Ben for your work. After the last major release I started to receive a ton of spam comments on my website like if I will turn of the ZeroSpam plugin. I get about 40-70 spam comments a day but before the new update the plugin had been blocking 99% of those.

It really can be this simple. Just install it and it works. You also could add additional features like ipstack and Google maps. Only thing that I'm missing after the last updated are these nice carts to get an overview. Would also be nice to integrate them into the WordPress Dashboard overview.

Each week I was having to delete hundreds of spam comments held for moderation but since installing this plugin only legitimate comments are getting through. I don't know how they do it but it seems like magic to me!

connects to services and websites that are not available, don't work or super slow. Couldn't get it to work at all. Don't waste time on this one.
