This plugin’s function is to check the IP address of the comment sender, gravatar, comment content.
How this plugin works : 1. Getting IP blacklist from stopforumspam.org This step determines the IP is a spammer or not by checking the IP on http://api.stopforumspam.org/api?ip=(the IP sender) using curl. The result will be appear on the form of .txt Non spammer IP will be marked by “no”
<ol>
<li>
Validating the gravatar Access https://secure.gravatar.com/avatar/(encoded email) Later,you can get the data of the registered email by using curl.
</li>
<li>
Validating the comment content Create hook on ‘wp_blacklist_check’ to check if the content of the comment contains the word listed on the Comment Blacklist on wp-admin Comment Blacklist is stored on Beon Intermedia’s server that is copied on the user’s wp-admin. User can add and delete the keyword listed on Comment Blacklist from wp-admin. Meanwhile, user can see only the keyword of Comment Blacklist on http://db1.andhikamw.com/ The updated Comment Blacklist keyword is shown on the column ‘update_secure_discussion’ of wp-option table
</li>
</ol>
After the comment is submitted, the plugin will determine whether the comment is a spammer or not from its IP , gravatar and comment content. Next, this plugin will change automatically the status into approve, moderation, or spam. However, the user can change the default status by himself on wp-admin (sub menu ‘Beon Comment Option’) as shown on Screenshot_2.png At the end, the plugin will force the default status (generated by the plugin) into the same setting of the wp-admin (managed by user) by using hook ‘pre_comment_approved’
