In a way I found sketchy/scammy aspects of Roblox helpful to educate my kid about that sort of thing. Early on a classmate scammed her out of some item on AdoptMe, nothing monetary valuable but it shook her and really caused her to think critically about online transactions and security. These days the friend group talks about IP bans and account bans so we did a good session about what IP addresses are, how they work, etc. She also did temper her expectations on how attached to get to the main account since it can get hacked or locked etc.
