Magento Observer to block spam orders not working

Question

I'm facing some issues with orders placed by bots.

I noticed that all orders are made by a specific phone number and also by a specific street. So I looked for a way to block orders that are made with that phone number or this street.

I found the following link https://www.ashsmith.io/2012/12/making-use-of-observers-in-magento/.
I followed the steps to create an observer with the event sales_order_place_before, to compare the parameters sent in the order to the parameters that I want to block.

1. I created the file Blockbots_Observer.xml on /html/app/etc/modules;
   
2. I created the file Config.xml on /html/app/code/local/Blockbots/Observer/etc;
   
3. Finally, I created the file Observer.php on /html/app/code/local/Blockbots/Observer/Model;
   

After all these steps, the implementation did not work (I am still receiving orders from bots).

Here is the code on files:

Blockbots_observer.xml:

Config.xml:

Observer.php:

What could be wrong with implementation? Any idea how I can fix it?

Answer 1

block the bot ip Address range from accessing your website.

in .htaccess file:

order allow,deny
deny from yourparticularip

or you can do it in your index.php

$banned = array('xx.xxx.x.x');
if(in_array($_SERVER['REMOTE_ADDR'], $banned))
{
exit();
}
