Re: Antibot Form Submission Composite Behavior

[Tom Eicher (von unterwegs)]

BTW I have found I can recognize many spambots by adding a form field with a 
common name like "message" and make that invisible using css display none. If 
the field is filled in, its no regular user...
Cheers, Tom.

Hi Martin, 

Thanks for your suggestion, the thing about the bot that was accessing my
site was that it it didn't give any user agent information which leads me to
think that it was malicious.

I've put together the following behaviour (included at the end of this) and
will use that for the time being to see whether its fit for purposes in real
life.

Cheers
Simon

Hi,

I'd recommend you to read
https://developers.google.com/webmasters/control-crawl-index/docs/robots_txt
.
I guess it is possible to disable the bot partially or completely.

About your behavior: it should contribute a JS file similar to this:
$(function() {
  var loadTime, focusTime, submitTime;

  $(window).load(function() {loadTime = Date();})

  $('input, select, textarea').focus(function() {focusTime = Date()});

  $('form').submit(function(){
 submitTime = Date();

 return isEverythingOk(loadTime, focusTime, submitTime);
  });

})
