Awesome plugin
By , for WP 4.1.1

One of our site got overrun by spammers and I installed this plugin. Right from the start it took out around 95% of the junk registrations.
I will have this plugin installed on all our site and strongly recommend it to use.

Keep up the good work :)

This plug in works so well, I am afraid to update it!

I used to get 15 or 20 spam every 4 or 5 days and it didn't take long to have 60 to delete. I even used two captcha programs at the same time. Nothing worked.

I have had comments make it through, so I know its working.. I suppose I could turn it off for a bit to remind myself how much junk is out there.

I have not had one single spam since installing this software!


Great Plugin!

I love this Plugin very much. It's great! E.g. the cache feature is a great enhancement! Together with the default Akismet plugin I have not any problems with spam user registrations now. But I have comments allowed only for registered users.

Several years ago I wrote the Advanced Block MOD für phpBB 3.0. It's a little bit similar to this Plugin.

Two ideas for this Plugin:
Please integrate Akismet support into your Plugin directly. So it would be possible to use your great log for Akismet, too.
Please be carefully with the spamhaus.org DNS IP-RBL. In past I have had some false positives with this blacklist (on phpBB boards). It's possible to prevent spam with DNS IP-RBLs without any false positives. But it needs carefully integration. DNS requests are faster than http requests. But the four webservices which you have integrated are doing a great job. So IMO there is not need for the integration of DNS IP-RBLs.

Excellent Upgrade!

This plugin keeps my website free from spam! Thanks a lot!

Truly The Best
By , for WP 4.1.1

This is the best plugin on the market when it comes to reducing your registration spam. There is no other plugin that does the job as well as Stop Spammer's and this includes many premium plugins such as Askimet and WangGuard.

If you ever have any sort of registration spam this should be the first if not the only place you look to reduce it to zero.

Such a hero in taking down spammers!

The plugin is so great that I feel sorry for poor spammers!
This plugin uses more than 25 ways to identify the spammers, when a spammer is identified it is blacklisted so it couldn't bother you again, but as the spammers change their ip regularly, each ip remains in blacklist for a period of time, so your blacklist doesn't get bigger and bigger every day.
Each successful login causes the ip to be whitelisted so it's not likely that you get locked out of your site.

Superb plugin

Have been using this plugin for quite a while now. Even before the previous version of it and it is the still best plugin against spam. Other plugins just didn't work as well and the the developer has spent a lot of time making sure to keep any spam that does get through, to to a minimal amount or none. Fantastic!!!

Good For Me
By , for WP 4.1.1

I cannot even imagine how much time this plugin has saved me. I tried many other plugins to stop spambots but this is the only one that actually worked for me.

This plugin is Great!

I installed this and within hours over 300 junk stuff were blocked! It was <i>very</i> simple to install and set up and has worked perfectly since.

Thank you Keith, for saving my site (and my sight)! Very happy to see it being updated! It is certainly worth sending you a cup of coffee or two!

Best Wishes for your continued success!

I am using this plugin for a long time on my sites.

I tried deactivating it for one day as a test and received ton of spam.

This plugin works great. And after new huge update it is even better than before.
