For example if I want to ban this
ферт
Where would I add that into the .txt file addon_anti_guest_dict.php ?
I was reading that the list needs to be kept in alphabetical order.

Hmm, where was you reading that?

An alphabetical order is more for your convenience. The list could be set up in any order, at least I've re-checked the algorithm and I see that it just compares all words or fragments with no reference to the order.

Still my question remains...
How do you place this into a .php file?
ферт
and have it recognized.
Do I need to encode it?

This is what I get if I paste it into any of my 3 code editing programs
'????',

I'm not keen on trying (and seeing if it works) on a live forum.
Thank-you.

I pasted it into regular Notepad or Notepad2 and it was saved correctly as 'ферт'.

So, I added those characters to the file and upon trying to save it from Notepad in Win7 got this message.
addon_anti_guest.dict.php
This file contains characters in Unicode format which will be lost if you save this file as an ANSI encoded text file. To keep the Unicode information, click Cancel.... etc etc

Another thing that happened is when I got the email notification of the reply that Tom322 gave instead of placing...
ферт
It placed...
(remove the spaces between & and #)
'& #1092;& #1077;& #1088;& #1090;'

So, I did go ahead and did add
(remove the spaces between & and #)
'& #1092;',
'& #1077;',
'& #1088;',
'& #1090;',
to addon_anti_guest_dict.php
This did indeed work.
You can find codes which you can add to your ASCII based dict file here.
google (cyrillic ascii table) for a start...

Thank-you very much for all your suggestions and help.

OK, so can you add wildcards... like this
'*ф*',
to
addon_anti_guest_dict.php

It all depends on the regional settings of your OS. Also, built-in Notepad is not the best tool for this. Most probably it will always offer to save file as Unicode - BUT if your forums are not Unicode (f.e. if they are Windows-1251), this is wrong. That's why we recommend Notepad2 or some other plain text editor.

Having Russian regional settings installed and Russian language, you should not have problems with this; however honestly I never tried it on Windows 7.

Also, I am not sure why do you try to put some certain fragment of the word - it's better to put fragments of the URL to prevent something. And this is actually not the best way to prevent from spamming, there is always work-around.

Wild-cards WILL NOT WORK for this add-on.

Ooops, ok sorry, just read the last line, wild cards won't work.

I don't have russian installed.
I'm now banning posts by guests with a random assortment of Russian/Cyrillic characters in the body.

My last question still stands, and I'm wondering if wildcards can be placed into phrases in the addon_anti_guest.dict.php file.

like
'Viag*', // would ban anything starting with Viag
'*ф*', // would ban anything with ф in the entire post body...

Star(phrase)Star doesn't work though. I'm wondering if someone knows of a way to do this though.

Try to put these fragments without asterisks i.e.

etc.

The Captcha can be configured, so Anonymous poster enters code only once per session
Hi Paul, I think I have solution.

At captcha image, you can set:
$private_key='everything';
$timenow=time();
$captchaText=strtolower($captchaText);
$_SESSION['captcha_key']=md5($captchaText.''.$private_key.''.$timenow) .'|'. $timenow;

At php captcha file:
$private_key='everything';
$allow_time=300;//5minutes
$captchaText=(isset($_SESSION['captcha_key']))? $_SESSION['captcha_key']: 0;
$captcha_time=explode('|',$captchaText);
$captcha_text = strtolower($_POST['captcha_text'].''.$private_key.''.$captcha_time[1]);
if(md5($captcha_text)!=$captcha_time[0] || time()-$captcha_time[1]>$allow_time) {
die("FALSE");
} else {
//continue
}

This way make captcha available only in 5 minutes.
You can set it smaller.
If you write a post that spend more than 5 minutes, javascript simply auto-refresh captcha.

Thanks for the solution, but currently, I don't see a practical ground for it to implement. Sorry, but I don't understand, what is it created for?
I'm sure in 99.99% of cases a guest user will enter Captcha immediately after making his post.
I'd rather escape making headache for my own for just 0.01% of the audience.

Is there a way to make Anti-Guest also work when users register?
I am getting spammers registering with URLs that include words I don't want used.

Any help appreciated.

Answering questions like "is there a way..." or "is this possible..." you should almost always expect an answer "yes".
In my practice, I've met nothing impossible regarding scripting PHP and input data.
And in miniBB, there is a very comfortable way of doing such customized changes without touching the core.

But - of course - it's only if you know what to do!
Hopefully miniBB provides lot of the free stuff to analyze and create something similar for your requirements.
