Final answer:
System admins use modules within a Content Management System or feedback management plugins to select and manage article feedback. These enable moderation and control over user comments, prevent spam, and uphold content quality.
Step-by-step explanation:
The module that allows system admins to select what article feedback is allowed is typically a part of a Content Management System (CMS) or could be a feature of a website's feedback management plugin. These tools allow administrators to configure settings to control the type and extent of user feedback that can be posted on articles. Most modern CMS platforms include settings or plugins that enable administrators to moderate comments, require approval before posting, filter out spam, and even ban certain users if necessary.
For example, in WordPress, a popular CMS, plugins like Akismet for spam filtering and wpDiscuz for comment moderation give admins a high degree of control over feedback submission and approval. The specific settings and modules may vary depending on the platform and the software's version being used, but in general, control over article feedback is considered a fundamental feature of website administration.
