Is Null’s Brawl safe for kids and what are the benefits of joining its Discord community?

My son recently started talking about a game called Null’s Brawl, which I learned is a private server version of Brawl Stars where players can unlock different brawlers and features. As a parent, I’m trying to understand whether it’s safe for kids to play and if there are any communities where players can get updates and tips. While searching online, I found some information about the game and its community servers where players discuss updates, events, and new brawlers. I also came across a page that explains how the Null’s Brawl Discord works and how players can join it to stay updated and talk with other fans. Has anyone here allowed their kids to play Null’s Brawl or join its Discord community? I’d like to know if it’s safe, moderated, and helpful for learning more about the game before I let my child join. For more information!
