What Is Content Moderation?
Content moderation is the practice of reviewing user-generated content (UGC) on internet platforms – social media, forums, and other online outlets – to assess its appropriateness based on the site's standards, regulations, or jurisdictional laws. This process is crucial for maintaining a safe and respectful online environment.
Importance of Content Moderation in the Digital Age
In today's digital landscape, the large volume of user-generated content has made moderation essential for internet platforms. With billions of users engaging daily, platforms face financial and reputational risks stemming from inappropriate or harmful content. Content moderation ensures a safe user experience, upholds community standards, and shields platforms from liabilities. It serves as a mechanism for overseeing the array of constantly evolving online content.
Types of Content That Should Be Moderated
Content moderation encompasses various types of media, each posing challenges that call for specific moderation approaches.
Text
Textual content, including comments, posts, and messages, is the most common form of UGC. Moderation efforts focus on screening out hate speech, offensive language, misinformation, and other harmful content. Textual analysis, often aided by natural language processing (NLP) algorithms, helps identify and manage such content.
Image
When it comes to image moderation, the process includes checking photos that users upload to spot any offensive content – like nudity, violence, or hate symbols. Advanced methods, such as image recognition and machine learning, are used to automate this task. Still, human oversight is necessary for a nuanced understanding.
Audio
Audio content, such as voice messages and music, needs moderation to filter ou offensive language, copyrighted material, or disturbing sounds. Tools like speech-to-text algorithms and sound analysis help in screening audio content. However, human intervention is often needed for context.
Video
Video moderation is complex as it involves analyzing visual content, auditory elements, and textual descriptions to ensure compliance with platform standards. Given the rich, multifaceted nature of video content, this type of media often requires sophisticated AI tools alongside human moderators’ efforts.
Types of Content Moderation
Different moderation types serve various needs and operational scales, blending automated systems with human judgment.
Pre-moderation
With pre-moderation, content is reviewed and approved before being published on a platform. This approach is commonly used in settings where quality control is especially important – educational platforms, professional forums, or children’s websites. It ensures that only appropriate and safe content is visible to the public, minimizing the risk of exposing users to harmful material. However, pre-moderation can slow down the content publication process and require significant manpower.
Post-moderation
Post-moderation involves publishing content immediately and reviewing it afterwards. This method is preferred by platforms that prioritize real-time user interaction, such as Telegram channels, social media, and live-streaming services. Post-moderation allows for dynamic engagement but carries the risk of inappropriate content being temporarily visible.
According to a Pew Research Center study, 66% of American adults feel that social media companies have a responsibility to remove offensive content after it's posted. This method balances immediacy with content control but requires robust mechanisms to address harmful content swiftly once detected.
Reactive Moderation
Reactive moderation depends on user reports to identify problematic content. Platforms like YouTube and Facebook use this method, where the community flags content they feel is offensive or non-compliant with the guidelines. This approach relies on community vigilance and can effectively manage content on large platforms without immediate pre- or post-moderation.
Still, the majority of the inappropriate content is detected by the machines. For example, during the third quarter of 2023, 8.1 million videos were removed from YouTube – and only 363 thousand videos were detected via flags from users.
Distributed Moderation
This type of moderation is based on users’ voting on content's appropriateness to influence its visibility or deletion. Reddit is a prime example, where user votes can elevate or bury content. Reddit's system allows users to upvote or downvote posts, with highly downvoted content becoming less visible. While this method decentralizes moderation tasks, it can also result in creating echo chambers or mob censorship in polarized communities.
Human-assisted Moderation
AI supported moderation combines intelligence with human judgment, commonly seen on social media platforms where dealing with complex content decisions is a daily job. Teams of human moderators review flagged content for violations of community guidelines and decide if they should be removed or allowed to remain on the platform. Also, websites such as eBay, Amazon, and Etsy employ human moderators to review product listings and user-generated content. They check that listings comply with the platform's policies regarding prohibited items, counterfeit goods, and inappropriate content. This approach strives to strike a balance between efficiency and nuanced understanding, especially when addressing contextual sensitivities.
Automated Moderation
Automated moderation involves AI algorithms to monitor, identify, and take action on content that violates policies. This approach is mostly used on big-scale platforms. For instance, Instagram utilizes image recognition and text analysis technologies to scan posts and stories for guideline breaches when moderating millions of posts. This system continuously learns from tagged and user reported content to enhance accuracy and efficiency.
Hybrid Moderation
This is the most popular approach to content moderation. Hybrid moderation combines various methods to optimize the moderation process. For example, Twitch uses a hybrid model, employing automated tools to flag content for human review, while also allowing community reporting. This mixed approach enables Twitch to manage the 15 million daily active users and their interactions.
Industries That Rely on Content Moderation
Content moderation plays an essential role across various industries in ensuring safety, compliance, and user engagement.
Social Media
Popular platforms such as Facebook, Instagram and Twitter heavily rely on content moderation to manage the volume of user-generated content they receive daily. With billions of users, these platforms utilize AI algorithms in combination with human moderators’ overview to sift through and remove harmful content.
For instance, on Facebook, a combination of “integrity signals” is used to rank each post. “Integrity signals” show how likely a piece of content is to violate Meta’s policies and include signals received from users from surveys or actions they take on Facebook – like hiding or reporting posts. This approach helped remove over 45.9 million pieces of harmful content from the platform in the second quarter of 2022 alone.
E-commerce
Major online marketplaces like Amazon and eBay employ content moderation practices to ensure that product listings meet legal and ethical standards. This involves monitoring for items such as counterfeit goods, inappropriate product images, or deceptive descriptions. Due to the scale of operations, these platforms often use a blend of automated tools and human supervision to handle the content.

Content moderation on news websites is crucial for managing user comments and discussions to deal with misinformation while fostering respectful dialogue. Major outlets like The New York Times and The Guardian have dedicated moderation teams and mechanisms in place to review user comments before they go live in order to ensure alignment with community standards and guidelines.
While AI mechanisms can ease content moderation, The New York Times still employs a team of moderators who manually review nearly every comment submitted across various articles. This is how a comment makes it to The New York Times website: first, a machine learning system called “Perspective” assigns it a score based on its appropriateness. Next, 15 trained moderators, all with a background in journalism, read the highlighted comments and either approve or deny them for publication. The decision is based on whether they meet The Times’s standards for civility and taste.
Education and Learning Platforms
Online learning platforms like Coursera and Khan Academy employ content moderation practices to uphold the quality and credibility of course discussions and user-generated content. The goal is to create a safe and respectful learning environment for students of all ages.
