Making spam-bots pay the price

Certainly JSecure is a great tool to prevent spam-bots and other undesired visitors from accessing the administrator login screen. However, everything is subject to improvement, and this is our proposal.

So, we were wondering if they could be sent away from the site. The answer is: NO. Because JSecure handles internal redirects only.

Other idea is to make them pay a price for try to access the administrator. So, this is not posible with the default code from JSecure.

How to identify search engine bots

During the development of one of our extensions, a member of the development team asked me how to authenticate a Search Engine Bot. The answer could be very easy: by useragent, but what if somebody changes the browser’s useragent?
