Sticky How to protect my forum from spam

In my experience of running forums since the days when Compuserve ruled the Internet, is that captcha systems only work to **% (YMMV) efficiency i.e. they can and are beaten regularly if you have a busy forum/site. I've had better luck manually configuring Q&A or a combination.

There are several popular blacklist services with APIs and online lookup such as:
www.spamhaus.org/
www.spamcop.net/bl.shtml

I've found this site pretty useful for quick manual reference but they also have an API:
www.stopforumspam.com/downloads/

What I'm wondering is if there is anything planned for a Kunena plugin for this or similar services?

Hi,

I'm very new to the world of web building and Kunena so please go easy on me!!

I've discovered and removed some spam from my forum and have deleted them as they appeared but now the ability to delete registered users has GONE!
I've had 3 appear in the last 24hrs even with CAPTCHA switched on.
One of them is not listed in my User Profile Manager and i'm concerned this one may have done something to alter my ability to delete users - is this possible??
How do i stop them please? I'm using Joomla 1.5 & have searched through the extension directory but am not sure which one is right for what i need - any suggestions here?

Thanks in advance for your help

Jo

I've installed Registration Validator - Thanks C0n!
Now for my other issue of not being able to delete the Spam that got through before this. As i mentioned above i could previously delete registered users and now this option has gone. Any thoughts on what's going on here?
Thanks,
Jo

Kunena has never possessed the ability to delete registered users. What version of Kunena are you using?

Hi,
I'm using 1.5.11

I thought i went into User Administration and the option to delete was at top right of the page (with edit etc.).

That's how i removed the previous dodgy registered users. I didn't take a great deal of notice until I went to do it the other day and the option is not there?? Am I going crazy!!

So how do i get rid of them now please?

Another one registered last night. not sure if it was before or after i installed the registration validator. They are not posting anything, just registering but when i look at the User Admin they are not listed there.
I'm freaking out a bit and am ready to remove the forum altogether as it's not very active and i don't have a lot of time to dedicate to this right now (unless someone can help me out with some advice of course)

Would this Spam be coming from facebook?
