Our findings indicate that individuals with toxic usernames are about 2.2 times more likely to engage in violent activity and to have their accounts terminated by moderators. Unmoderated usernames have the potential to validate harmful behavior and inspire others to do the same, but blocking offensive usernames ensures that nobody sets the wrong tone for interactions within your community before they even begin to chat.
It is the best way to protect your communities from harmful, disruptive, and unauthorized identities. We utilize our proactive neuro-symbolic method to look for the initial attempt to create a toxic username and to uncover hidden meanings in usernames.
Samurai moderates offensive identities that could alienate other users or encourage more abuse, while also making sure your communities are safe from inventive hostile attacks.

You can pass any username to the Username Moderation API in order to subject it to linguistic analysis to identify any disruptive, offensive, sexual or otherwise inappropriate language. With Username Moderation you can protect your communities and eliminate the risk of a toxic username setting the tone for the ensuing discourse within the community.

Samurai Labs uses a neuro-symbolic approach to dissect each username into its constituent parts, identify disruptive content and provide detailed information on what makes the username toxic. Crucially, Username Moderation can handle such text manipulation techniques as:
This way, Username Moderation is able to decipher even deeply hidden offensive meanings. Then, the Username Moderation classifies toxic content according to one of the nine toxicity categories:

Keeping schools and online learning safe by monitoring spaces and 1:1 chats to detect hostile or inappropriate conversations.
The purpose of Samurai is to detect and prevent violence, making it an essential asset for educational institutions that use platforms such as Webex for remote learning and communication.
Moreover, it has a positive impact on the schools’ reputation. By showcasing a reduced incidence of aggressive behavior, institutions can attract parents; preference and potentially enhance students’ performance in international educational rankings.
Keeping a top gaming community safe from toxicity and cyberbullying by identifying 30% more cases of community guidelines violations
● Over 130 violations of Community Guidelines were detected by Samurai Guardian each day
● 30% more Community Guideline violations were detected by Samurai Guardian and would be automatically removed when compared to human moderators.
● Less than 3% of Community Guideline violations were removed by moderators without being detected by Samurai Guardian.
Samurai’s Username Moderation detected over 12000 toxic usernames since the launch of a new game title during the game’s first months on the market
Over 3 months we processed over 340,000 usernames coming from Freedom Games. Some of them contained two or more identical usernames. After removing them, circa 270,000 unique usernames remained, out of which circa 12,000 were detected as toxic. It means that 4.27% of all username attempts were blocked because of violating the community standards.
Our data-based analysis shows that we successfully detected 88.8% of all toxic usernames (recall) with a precision of 99.22%.
Conducting counter-speech interventions powered by AI to reduce toxicity and community violations on Reddit
The main objective of our experiment was to test whether the level of cyberviolence on Reddit can be significantly decreased by community-driven, counter-speech interventions conducted by users in partnership with Artificial Intelligence.
Preparing a toxicity analysis of the official Discord communities for two adult games and preparing a bot for autonomous proactive moderation adapted to these adult communities.
Even if your game does not have a huge community focused on Discord, or you have a community that allows a lot of content that is not allowed on other servers – Samurai can help you. Thanks to toxicity verification and automatic moderation, you can effectively increase player retention and satisfaction when playing the game.
Bringing real-time counterspeech to the darkest corners of the web in order to evaluate students after completing the online course
Samurai Labs together with INACH created an exercise for the participants of a counter speech course in which AI delivered cases of hate speech in real-time on 4 chan with a high precision. Thanks to its ability to scan millions of conversations within seconds, the most important needs of the course were addressed and the following value was created:
AI Monitoring and Preventing Anti-Immigrant Hate on Social Media After Brexit Call
Samurai was engaged to develop AI models and analyze posts on Twitter and YouTube to detect violent speech acts against Poles. At the latter stage of the project Samurai’s data aim to power up HateLab custom dashboard for better measuring violence before and after Brexit, alerting authorities to trends and immediate threats.
Reducing personal attacks and cultivating healthier communities with autonomous counterspeech on Reddit
After analyzing the data, it turned out that without the help of penalties and bans, James reduced the subreddit’s aggression level by 19%. Moreover, the antisocial activity of those who received the interventions decreased in other Reddit groups as well.
There is reason to suspect that the interventions had a positive impact on overall user behavior rather than just motivating the audience to find another place to attack others.
Autonomous removal of offensive content from communities without exposing moderators to this stressful material and creating healthier and more positive communities.
Samurai Labs and Khoros faced the challenge of solving the issue and creating a system that would protect not only community’s users from harmful content, but also take care of the mental health of moderators who are most exposed.
Samurai Labs uses a proactive approach tailored specifically to usernames rather than general language toxicity detection. Our models were trained primarily on in-game usernames, which makes us the most precise solution for the gaming industry. There are dozens of methods people utilize to avoid detection which means that tackling them requires industry knowledge and purpose-built solutions. Our product easily deals with typos or other simple attempts at obfuscation but also with users’ more creative approaches to creating a toxic username.
Specialized knowledge is a necessity for effective detection of offensive usernames, which is an issue for some of the most popular AI models in the world, which have huge problems detecting more advanced, short names as they take a generalized approach.

While the API response does not provide scores it provides two parameters that can be used for customisation – the severity of the detected offensive content within the username and categories (e.g. ‘profanity’, ‘sexual’, ‘offensive’, ‘political’, and more) describing the type of offensive content detected. This makes it possible to target specific problem areas in more detail than general, broader solutions
Yes, you can. We can provide a free analysis of your usernames. The only thing you have to do is to schedule a call with us and then provide us with a sample of your username database. As a result, you will receive information about the number of toxic usernames in your community and an overview of the kinds of toxicity we detected.
Yes, you can. Our Username Moderation is often used before launch to act before the damage is done. It’s an even better solution than implementing it in an existing community because you prevent toxic behavior instead of reacting to it post factum.
