How to fight spam

Although from time to time the bands of spammers receive a setback from the security forces, it is such a round business that for every mafia that they imprison in jail, 10 more appear wanting fast income offering the last pharmaceutical wonder or promoting services of any kind in your site.

Well, to defend against spam we have multiple tools, which I compiled here to the delight of the respectable:

Oh, if you know some other method share it in the comments, this it's almost a public service.

Hashcash: to combat spam

Many will use the popular Askimet and others but it's good to add a tool more to combat the annoying spam .

Hashcash is a very simple and practical plugin. It uses a novel form of verification that who is going to write a comment, is a person, not a robot; rather what it verifies is that it comes from a web browser and not a server (robot). Unlike WP-SpamFree that works with JavaScript and cookies, it only uses the former.

It works in coordination with Askimet or without ; You have options to manage from the panel; and allows if a comment passes (unlikely, but possible), send it to the moderation queue. also works against unwanted trackbacks (references)

Although I have not checked it, nor is it in the available documentation of the plugin; would encourage me to say that it helps with the WordPress vulnerability 2.3.3 due to its operation.

Compatibility:

It is 100% compatible with XHTML standards, WordPress 2.3.3 and 2.5; Firefox 2.x, IE 7 (I tested it on 6 and it works fine), and Safari.

Recommended:

Since I used it (alone, without Askimet) I had no problems; and so other users on the plugin page claim the same fate.

Download Hashcash (latest version) 4.1

Install:

Please download the plugin and unzip. Then copy the file wp-hashcash.php to wp-content / plugins (directly to the plugins folder).

Activate the plugin. Optionally you can use Widget sidebar, but its function is only to offer public statistics (nothing technical).

Within the administration panel, you can configure the options, entering in: ] Options> WP Hashcash .

Does not require you to modify any code, it is automatically integrated (using the presence of 'wp_head' and ' comment_form [19659018] ' included in most of the themes.)
