This plugin adds an active letter counter, word counter, and comment counter above the comment box that provides a user with constant visual access to their input activity. Any comment that exceeds the word limit will result in a red change in its count as the user tries to type more words. If the users try to post anyway, a warning dialogue will appear below the comment box that will state the limit, and the comment will not post. Once the user edits the words that exceed the limit, the comment can be posted. User types are defined when the rule is created, isolating what user type is restricted by a given rule. Multiple rule types can be made if different rules are required.
The plugin never restricts or limits the WordPress default user types Administrator, Editor, Author, and Contributor. If the blog administrator creates a rule for any of the three roles separately (Editor, Author, and Contributor), then that rule supersedes the default setting. Other user types that may be seen in the user’s type dropdown do not default to WordPress and would require a rule to be created if limits are required.
This plugin also combines the ability to limit the number of comments the blog administrator allows. The defined limit is contained to each day, week, month, or per year. Once the limit is reached by the definition of the time span selected, an alert message displays the reason for not allowing further comments.
The plugin settings allow you to disable the flood protection notice provided default in WordPress, where a user is normally blocked from quick successive posts, resulting in a bleak 404 error. Along with this, a user is by default blocked from pasting the same comment, letter for letter, under any post. This can too can be disabled.
The latest addition includes the ability to activate a Comment Rules pop-up modal within the post. It can be deactivated in the settings but is active by default. It appears top left above the post’s comment box. You may create the rules to read anyway you wish in settings, but keep the text rules short as the sample text, or they will wrap and malformed the appearance of the window.
The plugin as a whole is very simple and uses nearly no system resources and is compatible with all tested blog add-ons loaded to the initial staging site. This includes membership platforms like Magic Members, MemberPress, Memberships Pro, Restrict Content Pro, LearnDash, S2Member and WooCommerce Memberships. Additionally, the plugin works in combination with any other WordPress module that requires a user to register before commenting. To clarify, for the plugin to work, a user must be a registered and active for the plugin to track activity. Logically, no plugin can monitor or limit unregistered anonymous comments. Guests cannot be controlled by the plugin limits, only registered users.
As of version 1.1.3, you now can from the metabox in each post, select the post not to be subject to the limit rules saved in the plugins settings. This has been a repeat feature request.
As of version 1.1.8, an administrator can optionally enter a global value in the settings panel, to limit the total number of comments allowed on all posts. If the field is left blank, the default value of WordPress is maintained.
Notes: This plugin will not work with wpDiscuz where it uses its own hook and templates. If the limit is set to two comments in 24 hours for example, but one was deleted by the moderator, the subscribers comments will now show another comment remains. Previously, any comments in the trash within the limited time was counted against the subscriber.
The plugin’s language support includes: English, Spanish, German, French and Russian.
<h3>Using in Multisite Installation</h3>
<ol>
<li>Extract the zip file contents in the wp-content/mu-plugins/ directory of your WordPress installation. (This is not created by default. You must create it in the wp-content folder.) The ‘mu’ does not stand for multi-user like it did for WPMU, it stands for ‘must-use’ as any code placed in that folder will run without needing to be activated.</li>
<li>Access the Plugins settings panel named ‘Limit Comments and Word Count’ under options.</li>
<li>Configure your settings with two different error messages and save settings.</li>
