The method to it’s madness is fairly underhanded to adults, much more so for its’ intended audience.
I wish I could find the video that did a basic deep dive on all (negative) aspects of the roblox community, from the robux, to the game makers potential for being exploited, and the oddly nft/stock market of cosmetics which are a massive fomo money sink. It wouldn’t be so bad if it wasn’t aimed at children, but because it is, that only makes the handful of bad/fringe cases even more unsettling.
It’s no big secret that kids are dumb enough to try and get robux for free from almost any link saying they can online. But the incentive is there for them to try.
Removing roblox from a kids library is a good thing for peace of mind. Plus there are plenty of other games out there to play with friends and depending on how they spent their time on roblox, it likely wouldn’t be terribly hard to match to another game within whatever genre they were playing.
