Meaning

A troll or griefer who deliberately disrupts online communities, chat rooms, or livestreams.

荒らし (arashi, from 荒らす, to lay waste to) is the Japanese equivalent of 'troll' — someone who intentionally disrupts online spaces. This includes spamming chat, posting inflammatory comments, griefing in games, or generally trying to ruin the experience for others. 荒らし has been a fundamental concept in Japanese internet culture since the 2channel era. Moderators work to ban 荒らし, and communities develop their own anti-荒らし strategies. The term is universally understood and carries strong negative connotation.

Examples

1. チャット荒らしがひどくてモデレーターが大変そう。 The chat trolls are so bad that the moderators are really struggling.
2. 荒らしはスルーするのが一番だよ。 The best way to deal with trolls is to just ignore them.
3. 荒らしのせいでコメント欄閉じることになった。 They had to close the comments section because of trolls.
