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 :)
