What is vB Bad Behavior?
This is an integration of the Bad Behavior software with vBulletin.

What is Bad Behavior?
Bad Behavior is a PHP-based solution for blocking link spam and the robots which deliver it. Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site's load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.

Visit http://bad-behavior.ioerror.us/ for more.

Features
For more information on the features of Bad Behavior (and subsequently this mod) please go to Bad Behavior's site:

http://bad-behavior.ioerror.us/documentation/benefits/

For features related to the mod itself, please take a look at the screenshots.

This mod should work with the entire 3.x series (well, beginning with 3.5), but it's only been tested on 3.8.x. I'm not sure if this works on vB 4.x yet, as I've not tested it - but if you try it out, let me know!

Installation
1. Extract the contents of the zip file.
2. Upload the contents of the `upload` folder to your forum root.
3. Enter your AdminCP and go to Plugins & Products > Manage Products > [Add/Import Product]
4. Import the product using the `product-vb_badbehavior.xml` file.
5. Configure the mod in AdminCP -> vBulletin Options -> vBulletin Options -> vB Bad Behavior Options

Upgrading

vB Bad Behavior
In many cases, all you'll need to do to upgrade is follow the installation instructions above.

The only difference, will be you'll need to allow the files to overwrite. Also, when re-importing the product file, you'll need to set "Allow Overwrite" to "Yes".

Bad Behavior
Bad Behavior's files are at `/includes/bad-behavior/`. If you wish to update manually go to:

http://bad-behavior.ioerror.us/download/

And download the latest development version. Extract the zip, and upload the contents of `bad-behavior` to `/includes/bad-behavior/` allowing the files to overwrite.

Versions
The current version of Bad Behavior this mod is using is: v2.2.14
The current version of Bad Behavior (development) is: v2.2.14

I think the explanation of what BB is should include that BB also blocks a large number of content scrapers and malicious bots. This saves bandwidth costs and increases security.

I find these very important aspects of BB and adding this will increase the number of sites that install BB.

Does the whitelist also include Google's MediaBot (for AdSense)?

I have enabled Bad Behavior again. It immediately freed up my server from an insane server load. Server load went from 38 to 0.7 almost instantly.

I do see a valid members blocked. Details:

A very large number of these:

I dont understand how it is possible that a large number of valid user post more than 2 days after GET.

A large number of these:

I see these valid members are using proxies like TOR and similar.

Feature request 1: for the log: filter per key, so that it is possible to see all entries except those with key 00000 and key 2b021b1f. Or just view all entries with a certain key. That makes it much easier to see the similarities of the entries with the same key.

Feature request 2: Alert the admin which members have been blocked by BB and why. This makes it easier to detect problems with BB and forum accounts registered by bots. I think the optimal way to notify the admin is by PM.

Feature request 3: Trace IP directly from the log.

Feature request 4: related to FR 2. If bbuserid is present in headers then show link to user profile in the log. This makes it easy to check if the blocked members was a valid user or not.

Running in debug mode and checking out the queries exposes this error on forum home:

Its really amazing to see how many attacks, malicious bots and content scrapers this mod is preventing. No wonder my server was under such heavy strain. While it was at crawling pace before, its lightning fast now.

Regarding: POST more than two days after GET

Looks like this is happening if it's been 48hrs + between the screener cookie and a form submission:
PHP Code:
        // Posting too fast? 5 sec
        // FIXME: even 5 sec is too intrusive
        // if ($screener + 5 > time())
        //    return "408d7e72";
        // Posting too slow? 48 hr
        if ($screener + 172800 < time())
            return "b40c8ddc"; 
Not sure about that at this point. EDIT: I believe I know why now, will try to address this in the next update.

--

Regarding: Required header 'Accept' missing

The browser/user is sending:
Code:
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3
But not sending "Accept:" for eg:
Code:
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
I'm not sure if that's an issue with Chrome, or what.

--

Regarding: IP address found on http:BL blacklist

Not much to do about that one, as far as this mod IMHO - since that's using data from projecthoneypot.

--

On the feature requests, I'll try to get those in the next release

Hmm. It appears this occurs when BB is trying to set a cookie using the bb2_screener_cookie() function. This could be caused by output from vB/a hook before BB is called.

If anyone runs the vbseo sitemap generator, check it still works
Mine needs an extra kick every day now since running this mod
I have to go into the sitemap control panel and do a manual generation to finish mine
With this mod disabled, no problems

Apart from that, this is still dropping idiots like there is no tomorrow
