Spambots are a huge issue, this kind of security ought to be part of Joomla's framework. Does a fantastic job, lets me know when any known spammer IP attempts to register, etc. Love this extension.

We had massive problems with automated spambot user registrations.
After installing this plugin 99,5 % of Spammbots can't register any more.

Thank you!!

After my forum got overwhelmed with spam I've decided to try this plugin to block the spammers already at registration level.
I have to say I'm impressed with the result. During the last two weeks the plugin catched almost 1500 attemps, all with the StopForumSpam engine.
I've even disabled the captcha to see how many go through.
A few managed to register but those usually got caught by another spam extension.
I can live with that :-)
Thanks!

It works beautifully; it stopped 15 spambots in one day.

I'm used to having to figure out why an extension doesn't work with my configuration, what needs to be tweaked, where else I have to go for keys, figure out why they don't work, etc.

With this extension, all I had to do was install it and check a couple of settings, and then it just worked.

This should be a part of the core functionality of joomla!

Stopped the spam attacks overnight.

I tried others, but no other catches the spammers so efficiently during registration as this. Most spammers are stopped via the StopForumSpam engine. So make sure that is enabled.

Big thank you to the developer.

This plugin has efficiently helped solve our problems with spambot registrations. The fact that blocked names are stored in a table is very helpful. By reviewing the table contents, you can on the one hand track the efficiency of your "filtering" and on the other hand you can verify that you don't block real users.

This is the one. Look no further.

I'm using Kunena forum on Joomla 2.5. It became unusable due to registration spam. I tried every other anti-spam add-on and extension I could find, and almost gave up. Then I tried this one, and it works, stopping all but 5 spambot attacks. It stopped and recorded an amazing 4,295 spambot registration attemtps since installing it on December 12, 2012. Today is December 31, 2012. (That's an average of one spambot attack every six minutes!)

Almost all spam was stopped by the extension using "StopForumSpam" verification. This is demonstrated to me by recording spambot attempts in the handy table added to the database. About a dozen were stopped by the "SpamBuster" check, and three by the "ProjectHoneyPot" check.

This is a wonderful extension that has actually solved the seemingly impossible problem. Highly recommended. Thanks guys, your saved my project. Happy New Year.

Upgraded a 1.5 site to 2.5.7 as the older site had attracted spam registrations. Reported these ips to spambusters and checked with other sites. So these were suspect spammers. Added SpamBotCheck and this extension has begun to notify of repeat attack attempts from my known offenders so I am happy that this simple to use plugin should get recognition.

Easy to configure and works.
Use it and sleep some.

After I install this small plugin, it can prorent almost over 20 spam registration attempts every day! Think about this: how many spambot will slip into my website if I have not install this plugin?

So I think this plugin is wonderful! Try it if you got too many spam posts on your Kunena forum.

I am in the process of developing a Joomla website. Apart from backing up, security and the prevention of undesirables (i.e. spammers) registering and logging onto the website is my main concern. I knew of the StopForumSpam database and wanted a plug-in that could use it. SpambotCheck can use the StopForumSpam database as well as other databases.

The author is contactable and the project is very much alive. When I found some minor bugs the author was very quick to fix and bring out a new version. In fact the author also implemented some extra features that I requested very quickly. The current version (1.1.6) works very well.

Joomla administrators have the ability to set whether each user is checked only on registration or on registration and every login, for peace of mind I prefer (and recommend) to check on registration and every login. Normal users can register and login with no problem.

However spammers who have their details in one or more of the databases that SpambotCheck is configured to check (again set by the Joomla administrator) are prevented from registering and getting added to the user database of your site in the first place. Should a user be added to one of the spam databases after registering at your site then they will be caught next time that they login. A polite message (which Joomla administrator can customise to their own requirements) is issued depending on whether it's a registration or a login denial.

I have no connection with the author at all. Just a very happy/satisfied user of their plug-in.

This is an essential plug-in for any Joomla site to help the fight against spammers!

I was getting spambot registrations at the rate of at least one per hour, and was having to continually monitor my site and delete them as soon as they appeared. I had recaptcha and opt-in email enabled for registration, but apparently they found a way past the controller. Anyway - I installed spambotcheck, and it is handling the spambots like a pro. I set it to registration only, and only check the IP. I've doubled checked several of the IP blocked, and they all have been from strange locations and are on spambot lists. Thanks for a great plugin!

I don't have an enormous spambot problem, but it's enough to have to keep going into the admin area of the site to clear out spam registrations. I installed this plugin 24h ago, and the spam account attempts have stopped dead in their tracks (and I know real users can still register).
Easy to install, easy to configure and effective.

The best extension of it's kind.
No more words needed to define it .
thankyou very much.

I was getting very frustrated with spammer registration and spammers adding ads and posts. Make sure you select the webs where you want the checks done as they are not put by default so you can choose which ones to check against. Gone down to zero spam!! My only wish is that I could sent a rude message to them when they register!!!

this is a kind of plugin i wanted so far, it works with honeypot spam blocker and it has ip whitelist option coz last time i use plugin just for honeypot rules, even my IP got block, now i can use this white list feature and it was working excellent on my website!

Very very thanks for this tool.
It is very useful!
Easy to use and install. Anti-spam links are updated minute by minute.
From today: favorite

Great tool to stop new spam users to my new site. Works excellent en is very easy to install. I will use it also for my other websites!

This extension does exactly what it says it does. Installation and configuration was quick and easy. Works really well.

have this extension to run since a few weeks on a very frequented board without any problems

This extension works, with basic Joomla setup, it doesn't work however with CBuilder, and worst of all I was not able to get rid of it. When I disable it, it still shows up on my login page, and when I removed the extenstion my whoe site crashed. I'm not sure how the code is linked to the database and the Joomla core, but at this point it drives me nuts because I do not want it and I do not need it and I cannot remove it without consequences. It doesnt also offer any way for trsnslating the screen prompts to another language.
