The Trust & Safety Glossary

A

Accuracy

Refers to the degree to which automated or manual moderation tools make the correct decisions. Sometimes measured as an inverse of the false-positive rate. Read more. 

Adversarial Behavior

General term for unwanted on-platform behavior

At Scale

A reference to the volume of violative content and the flexibility of the system with the capacity to properly moderate the content.

B

Ban evasion

The act of bypassing platform moderation actions or circumventing a platform ban, often involves the creation of at least one additional account.

By creating new accounts, threat actors can return to a platform whose policies they have violated, in an effort to continue to do harm.

Banning

Permanently removing or blocking a user from the platform.

Intentionally misleading information that is shared and broadly distributed (disseminated) with the purpose of misleading or deceiving an audience. Often used as propaganda, disinformation has been widely used to sow public mistrust, influence elections, and legitimize wars. This is generally an organized, orchestrated effort.

A distinction should be made between disinformation – the intentional dissemination of misleading content, and misinformation – non-intentional distribution of misleading content.

Distributed Moderation

A type of content moderation where no individual person makes the moderation decision, rather community members (individual users) vote to determine if an item should or should not be allowed on the platform or forum.

Duty of Care

In the UK’s drafted Online Safety Bill, online platforms have a Duty of Care to assess risks to their users, put policies and procedures to minimize that risk, and take actions to keep users safe.

H

Harmful Content

Any text, image, audio, video, or other content posted online that is considered violative, malicious, deceptive, illegal, offensive, or slanderous.

Hash Database

In Trust & Safety, organizations such as NCMEC aggregate databases of image hashes that are related to various offenses (in this case, child safety). Platforms can then compare image hashes from their content to hashes of known malicious content (such as CSAM). This way, moderators do not have to view and analyze a potentially harmful piece of content and can compare its hash to that of recognized images.

Read more: Content Detection Tools

Hashing

Technology that creates a unique, fixed-length string of letters and numbers to represent a piece of data (often an image). The hash is non-reversible, meaning an image can’t be recreated from its hash.

Read more: Content Detection Tools

Hate Speech

Any expression or online content that incites, discriminates, justifies hatred, or promotes violence against an individual or group. Given distinct cultural and linguistic nuances, the detection of hate speech is often a complex task requiring regional and linguistic expertise.

Human Intelligence

The collection of intelligence by means of interpersonal contact.

In Trust & Safety, specialized teams use human intelligence to infiltrate threat actor communities and proactively identify their means and methods.

I

Impersonation

Apps or websites that are intentionally created to resemble existing apps or services or appear to be a part of the user interface in order to gain access to personal data, passwords, bank accounts, etc.

Impersonation Of Individuals

The creation of fake accounts, often using a target’s name or photo, in order to cause harm to that individual.

Intelligence

In trust & safety, intelligence is used to proactively alert platforms about impending risks, and to inform better moderation decisions.

Intelligence Desk

Internal or vendor teams that are responsible for on- and off-platform intelligence collecting in support of the Trust & Safety team’s efforts. Utilizing a broad range of tactics, including OSINT, WEBINT, and HUMINT, the team detects new threats and trends, identifies tactics, techniques, and procedures (TTPs), conducts investigations into suspicious account behaviors, “red teams” platform policies, and more.

K

Keyword Moderation

A form of content moderation that flags the instance of specific, potentially violative keywords used in text, audio, images, or videos posted on the platform. This type of moderation is limited in that it often lacks a contextual understanding of the keyword’s use, and requires constant updating of new violative keywords.

M

Malicious Content

Content that is created or shared with malicious intent. Includes but is not limited to child sexual abuse material, nudity, profanity, sexual content, bullying, terrorist content, violence, and disinformation.

N

Non Consensual Intimate Imagery

Sexually-explicit images that were either acquired unknowingly or unlawfully or were taken consensually but shared or posted online without consent.
NCII also include the sharing of intimate imagery beyond the scope of its intended use (ie. leaking intimate images shared on one platform, across other platforms)

 

O

Online Safety Bill (UK)

The UK’s Online Safety Bill is upcoming legislation that will require online platforms to take proactive action to keep users safe. The Bill outlines illegal, and some legal but harmful content that platforms will have to act against. The Bill’s current draft is in Parliament and is expected to pass by the end of 2022.

Online Sexual Harassment

Sexual harassment or misconduct that is conducted online. This is disproportionately aimed at women and/or members of the LGBTQIA+ community.

Open Source Intelligence

Also knowns as web intelligence (WEBINT). Intelligence that is collected via publicly available information online.
In Trust & Safety, open-source intelligence is used to gain a contextual understanding of harmful activities, enabling proactive content moderation.

P

Policy

The content policy of a user-generated content website defines what can and can’t be posted to that specific website. Also known as Content Policy or Community Guidelines.

Policy Analyst

Member of the policy team, responsible for analyzing and examining the effectiveness of a company’s content policies.

Policy Enforcement

The team responsible for enforcing the platform’s content policies and taking action against violative content.

Policy Specialist/Policy Manager

Individuals in the Trust & Safety team responsible for establishing the platform’s community guidelines and defining what is and isn’t allowed to be shared on the platform.

Involves collaboration with internal teams as well as external agencies such as law enforcement, regulators, and industry partners.

Proactive Moderation

A form of content moderation that aims to detect malicious or violative content before it is seen or reported by others. Utilizes various techniques, including automated detection and intelligence collecting to identify the violative content before it has a chance to harm user safety or platform integrity.

Previously used only to detect illegal content like CSAM and terror, pending legislation may require platforms to proactively moderate harmful, not just illegal content.

See Harmful Content Detection

Proactive Removal Rate

A metric that indicates the rate at which action was taken on content or accounts prior to being posted or reported by other users.

Calculated by the number of proactively moderated items divided by the total number of moderated items.

R

Reactive Moderation

A moderation process that relies on a platform’s community or other individuals to identify and flag content that may be in breach of a platform’s policies. Due to its reliance on the community, violative content is often seen by multiple users, before action is taken.

Recall

The measure of how much of a platform’s malicious content is picked up by its moderation systems.

Calculated by the number of correctly identified malicious items, divided by the total number of malicious items on the platform. For example, if a platform has ten malicious pieces of content, and AI identified seven of them, that AI had a 70% recall rate. For most automated detection mechanisms, recall and precision are inversely correlated.

Reverse Engineering

A method or process where attempts are made to replicate a system, process, machine, device, or software. Used in cybersecurity and red teams to find malicious code in software, websites, and apps.

T

Tactics, Techniques, and Procedures (TTPs)

Generally provided by intelligence providers or internal intelligence desks, TTPs are a description of the techniques used by bad actors to conduct harm. In Trust & Safety, an understanding of bad actor TTPs can provide teams with the insights needed to proactively detect and stop on-platform harm.
