Anti-spambot: disallow registration if referer page = register.php

This is an extra percussion to limit the spam on your forum. This product is likely to function on vBulletin 3.6.x to vBulletin 3.8.x.

What does this product do to limit potential spam?
After doing research on my forum, I noticed 80% of all spambots visiting my register.php page, used the same register.php page as the refering page. This is automatic spambot behavior, because it's likely your members click the register link on your forum index and not on the same register page.

[EXAMPLE] Request headers for: www.myvbulletinforum.com/forum/register.php

Request www.myvbulletinforum.com/forum/register.php
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding gzip, deflate
Accept-Language en-us;q=0.7,en;q=0.3
Cookie bblastvisit=1370691249; bblastactivity=0
DNT 1
Host www.myvbulletinforum.com
Referer www.myvbulletinforum.com/forum/register.php
User-Agent Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; FunWebProducts; .NET CLR 1.1.4322; PeoplePal 6.2)
It's likely in doing so, because a lot of websites block targeted entries if there is no refering page used (general bad idea, though). With this product, they will get served a blank page when trying to enter your register.php page with your register.php page as a referer.

It adds an extra layer of security, next to your other security measures on your bot. On my forum, 80% of those requests get a blank page served and not even had to rely on my other anti-spam measures on the actual register page. Also note that the register page is close to 30kB to load, this product will save you a lot of bandwidth if your register page is also visited 80% of the times by spambots with a referer to your register.php page.

Conditions:
- The spambot/user request the page: www.myvbulletin.com/forum/register.php
- The refering page of the requested page is also: www.myvbulletinforum.com/forum/register.php

Result:
- The spambot/user gets a blank page of 0kB served
Is this all I need?
This product can work great against preprogrammed spambots, who are programmed to search on the internet to forums with an existing page on the pagerequest of www.myvbulletinforum.com/forum/register.php and variations. This product won't help against human spammers.

No settings required, all you have to do is install the product.

This just makes my registration page white, I have to agree to a TOS then click register again so that might be the issue

I installed 1.0 and had the same problem. I just installed the update, so hopefully the problem is gone.

FWIW, I've tried a bunch of different anti spam-bot registration add-ons with limited success. This add-on has shut them down completely. Hopefully real users will be able to register successfully once again with the latest fix.

If 1.1 does not serve you right too, I would like to recommend: Is Bot: Registration Time Check (works perfectly on vB 3.8 too)

After 1.1 the spam bots are able to register again. BTW, I'm already also using the IS Bot mod...it helps a lot but doesn't kill them all.

I found a typo in 1.1, which caused that. Product tested and updated to 1.2

1.2 doesn't seem any better. I still have the same type of spam bots registering as I did with 1.1.

This product stops a lot of spambots from loading the registerpage, but it will not work against ALL spambots. Other spambots will have no referer page in their http request, but blocking anything with no referer can result in blocking legit users with unusual browser settings or proxies.

Have you checked out vbStopForumSpam?

You can use this in combination with Spambot Stopper - Prevent Spambots from Registering - vBulletin.org Forum or Spammers Suck! - vBulletin.org Forum.

vbStopForumSpam caused a lot of problems for me. It actually disabled a bunch of stock functionality on 3.8.7. I'll try again but I have my doubts.
