Roblox's complicity towards their massive child predator problem is criminal. Not only are they fighting like hell to keep over 150 child predator lawsuits in arbitration, they are now eliminating global user IDs, which is one of the only ways we can track predators and criminal networks throughout Roblox.
This will massively stunt the success of investigators who hunt child predators on Roblox, and I suspect they know that. It also prevents developers from creating ban lists and keeping known predators out of their games.
Roblox doesn't care about the safety of your kids. Keep them off!
Roblox games will no longer use global User IDs, instead users will now be given a new User ID unique to each game they join.
