  Online game forums are popular to most of game players. They use it to
communicate and discuss the strategy of the game, or even to make friends.
However, game forums also contain abusive and harassment speech, disturbing and
threatening players. Therefore, it is necessary to automatically detect and
remove cyberbullying comments to keep the game forum clean and friendly. We use
the Cyberbullying dataset collected from World of Warcraft (WoW) and League of
Legends (LoL) forums and train classification models to automatically detect
whether a comment of a player is abusive or not. The result obtains 82.69% of
macro F1-score for LoL forum and 83.86% of macro F1-score for WoW forum by the
Toxic-BERT model on the Cyberbullying dataset.
