The plugin works decently, but the commercial tricks are an absolute disgrace. I installed it to see how it goes. The first 5,000 login controls per month are free. I though it would indeed control the first 5,000, then stop controlling. Instead, from the 5,000th, the plugin simply refused access to all users, virtually blocking my website. Only the admin account was able to connect to remove the plugin and enable the users back in. That’s not how people is going to pay for it, instead you got a perfect way to get removed from potential consumers.

Initially this plugin processes the request after a cache plugin so if you are running a cache plugin, blocked IPs will still get served the page by the cache. I got a message this has been fixed. Excellent customer service from this company.

I sent a mass email out to just a small segment of my newly registered free-account subscribers, only to have MailChimp come back and tell me that some of them were invalid. I had questions getting started, I reached out to support and spoke to Dennis. He answered all my questions, and when I told him I wanted something that worked with WordPress so that I didn’t have to customize my 3rd party plugins to be compatible, he gladly shared there was a WordPress plugin already in existence. IPQS has been very easy to work with, and this plugin was very easy to install. Thank you everyone at IPQS. I look forward to a long working relationship with your team.

We had the worst issues with users and even lots of fake orders on our woocom site. In just a few clicks we enabled protection and bam, everything is good now. From our experience – it’s a pretty versatile solution and should be able to solve any kind of bad behavior.

Been having some issues with bogus users and some chargebacks through WooCommerce. Decided to give this plugin a shot. So far good experience. Lots of settings to customize the plugin and it’s been a huge help in catching the bad users that keep creating new accounts. I’ve also been able to stop most of the chargebacks so that’s a plus too.

Our sites been plagued by fake users and bots using completely fake user info. We’ve tried every service and most were able to stop some of the fraud, but this plugin has stopped every bad user. Our team is really happy that they can spend less time reviewing users. Plugin worked great from the start and we even contacted support to clarify a few things and they responded right away.
