It can be adapted to prevent spam in other extensions.
It works better if integrated with Akismet. You can get an akismet key at akismet.com. And if you think that you have to pay for a key, better look again and you will find that you can get it for free.
The extension adds a reference to the developer's site, but you can remove this in configuration.
Thanks for the review. But I have to say that turning on "Use plugin" has nothing to do. As there is no plugin for R-Antispam yet.
What you should have set is the Akismet integration with an Akismet key. That's what should have stopped the spam registration.
PS: If you want to remove the bottom back link there is an option in configuration for it.
Akismet integration makes this a must-have extension.
I have other protection installed but this extension stops things 1st up.
If you use Kunena Forums then use this too.
Integrating with Akismet provides nearly 100% spam prevention.
The best part is that in the past month it has trapped over 75 spam attempts and only 2 got through. Of the two that got through they were recognized as spam but were below or at the allowable threshold, which can also be adjusted.
I can't comment on the support, because this module has worked so well and is so easy to set up that I haven't needed to use them!
The Long; I'd happily give this package 6 or more stars if I could... I was a bit skeptical when I first installed this, thinking it may cause me even more work than I already have. But I was wrong. Worked Great right out of the box. It has caught hundreds of spam messages on my Kunena Forum with only 1 false positive (that I have seen), and that is pretty good by me.
Great work... Try it out!
I really like to contribute this developer.
Hats off :)
It really got to be a pain to have to permanently delete 10 to 15 messages a day. I installed SPAMFIGHTER, and it integated with Kunena Forum immediately, the amount of SPAM I had to actually delete from the forum dropped from 15 to 1, and with the ability to block IP addresses, much of what was formerly posted, is now blocked.
I can't say enough good things about this extension.
My only "complaint" is that it's a "black box". It would be good to understand how it works -- e.g. what legitimate postings might it trap in error.
SpamFighter uses the spam detection algorithm used by most e-mail clients and servers. It is a bayesian algorithm, a probabilistic method. Every time you report a message as spam, it recalculates the probability of every word of appearing in a spam post.
