I as security use this plugin over a periot of 2 years and found it good, we run a online news-paper that got a lot of fake inlogs on ower redactie-members, but this plugin collect them all and put them in the blacklist. What I like is to put in the IP’s *.*.*.*-*.*.*.* now we use the *.*.*.*/** this works also but is more better.

Powerful – Easy to use – Works as advertised. This plugin really helps to prevent spammers. I installed it primarily to help block spam registrations, and it works great for that. I can see the results in the log report. Clearly works well to help stop spam comments as well.

Great plugin before, but now it produces error messages for PHP (version 7) and doesn’t work flawlessly anymore.

It was good for previous versions of PHP.

Edit: fixed, see below

So far, so good –

I’ve had nearly 200 spam attempts at logging in – all refused entry – and I watched a couple of genuine users logon using the simple arithmetic challenge – all got in.

This plugin makes you feel like god!

The plugin is great and blocks a lot of spammers!
But somehow there are still spammers comming trough.
I checked up the IP’s and looked over to the country and blocked them, but still they continue to try to register on my website….

Have been trying to block the spammers for a few months on our new website.
This plug works well!
