Weird Phenomenon in Brawl Stars

Looking at other people's posts, I've been seeing a lot of this recently.. I suspect it's an advertisement for hacks. Ignore and report..

That's a hack. If you're playing solo, you won't encounter it if you just don't create a team.

Seriously, if a level 1 Shelly like that joins, I'd be flustered and lose my mind for a sec ㅠㅠ Lately, there have been frequent bugs where weird bots or troll users join when creating a team. I also encountered someone like that last time, couldn't kick them, and lost points because we lost, which was so unfair... Don't stress yourself out unnecessarily, just create a new room and play cleanly. You got this~!!

Hacks lolololol
