I’ve read about these concerns but my kid is 11 and on there all the time, often with me over her shoulder, and I’ve never seen any sign of it.
It’s a huge platform for kids so I’m sure there are some creeps but there are plenty of controls in place to deal with that and even so, again, I’ve never seen it.
The creeps are only part of the problem. The platform itself is deeply exploitative and harmful. It's full of "you can make games and get rich" messaging that's just a lie. To say nothing of even if you are successful, they will take a staggering cut, and may not pay at all.
