Is Bot: Registration Time Check · **Released**: 12-29-2006

This mod calculates the time it takes to go between these two pages:

/forum/register.php?do=register
/forum/register.php?do=addmember

The point is to try and prevent bots from registering at your forum when the time between the two pages is humanly impossible, assuming that humans actually take the time to complete the registration page.

Should a user be blocked from registering at your forum, an email will be sent to your vB webmasteremail address and the user will see the vB noregister phrase message, so no screenshot is necessary.

It is still fast. Let's say, it can complete 1 registration form in 1 second. Instead of doing one form every 1 second, it simply does 20 forms in 20 seconds.

In fact, it could be faster. Because while it is waiting for the web server to respond to it's HTTP request, it will be idling. So instead of idling, it can simply shoot off a few more HTTP requests to few more servers.

I'm really simplifying it here. I'm leaving out server response time and such. A well written bot can be much more efficient.

True, but most bots will do a grab and rub and move on to the next site. I have yet to see a bot that will backtrack after so many seconds to the same site. That would be a lot of http calls.

Nope. It's still the same number of HTTP requests. Requesting the reg form is one request. Submitting it is another request.

3 questions

1. Where do I change the time period?
2. what is the recommened time used by everyone?
3. Where are the settings for this after installed?

I answered you all of this in the other thread.

Hi,
I'm having problems with spambots submitting multiple requests to register.php?do=addmember; thousands per day.

Of course, since I use the human verification option with graphics etc., they are unsuccessful in completing any registrations. But the traffic is slowing down the server greatly and my ISP is pissed off.

Will this mod do anything to alleviate that issue? Once they are detected by this, does that in any way stop them from making more requests to register.php?do=addmember?

Yes it does, with some simple changes. Go see post #347 (on page 24) of this thread. Also read the posts following that for additional information.

Just to clarify post #347:

It should read:

Code:

<input type="hidden" name="isbot_time1" value="{vb:raw isbot_time1}" />

and not:

Code:

<input type="hidden" name="isbot_time1" value="${vb:raw isbot_time1}" />

... note the missing '$'

thalamus, Thanks for catching that. I've edited post #347 to remove the error.

It is not a VB3 engine, just a parsed copy!
