These mod menus often advertise features that are highly desirable to frustrated players:

Instead of risking your account, buy the Brawl Pass. It is the most efficient way to get Gems, skins, and PowerPoints. If you are free-to-play, save your Gems from the free pass every other season.

Even if you somehow dodge the ban hammer (which is rare), you are actively ruining the matchmaking pool. Using auto-aim mods or speed hacks in Power League or Club League isn't "trolling"; it's vandalism. You are stealing time and enjoyment from real players.
