An automated moderation service, Username Guardian by Samurai , was used to determine if a huge number of usernames were malicious. This service describes the maliciousness of user names as 'aggressive' including racism, homosexual disgust or violent language, 'vulgar' with typical taunts, and explicitly not vulgar but drugs and humans. It is possible to classify it into 'inappropriate', 'sexual', etc. using words related to physiological phenomena, and it is said that it also supports intentional spelling mistakes and Let .

When the research team randomly selected and analyzed 50,000 users with malicious user names and 50,000 users with harmless user names from each dataset, it was moderate with 'malicious user names'. It turns out that active users are 38% more likely to write maliciously than similar users with harmless usernames.

Users with user names classified as 'vulgar' or 'sexual' have a particularly high rate of making malicious comments, and 50% more malicious comments are made than users with harmless user names. He said he was writing. The maliciousness of comments is also characteristic, and users with vulgar usernames are most likely to make personal attacks (45% more than average), and users with sexual usernames make sexual harassment and sexual remarks. When the probability of doing so was the highest (250% higher than the average), the tendency of the user name was directly reflected in the remarks on the bulletin board.



There are some hypotheses as to why users with malicious usernames write maliciously. One of them is that 'warlike or suffering from personality disorder' is the reason for frequent attacks on other users. In addition, the theory that 'younger users intentionally choose a provocative user name and make offensive remarks on the Internet' and 'users with controversial names may be attacked by other people. In many cases, retaliation against it leads to malicious comments. '

The research team emphasizes that most of the malicious writing is generated by a handful of users. This is because only about 2.7% of users have malicious user names, and 58% to 65% of users with malicious user names did not post maliciously.

Also, this study does not include, at first glance, good writing, but practically harmful writing, such as 'concern trolling .' 'Concern trolling' is a type of spoofing that pretends to be an ally of a group, but expresses concern about things that are beneficial to that group, and conversely proposes actions that damage the group's credibility.

The research team then said, 'Study on malicious behavior and its prevention online is important because their involvement adversely affects mental health and increases the risk of anxiety, stress, depression and suicidal ideation. , Because it can lead to substance abuse and violence, 'he said, calling for efforts to prevent damage from malicious writing.
