This was actually apart of Jailbreak for a little bit. I know it hasn't been on JB for a while but It wasn't because of it being buggy (if I remember correctly). As a JB admin, I would this command whenever someone was constantly was breaking the rules and needed a refresher of the rules. The command's intentions are perfect and could definitively be helpful. The problem is just because you can force something on their screen doesn't mean they are actually going to read it. If all they have to do is click a button to remove it off their screen, then what's the point? There's no way to prove whether the command is actually efficient or not. Would it hurt to add it? No. Again, it's difficult to see whether the command would help. Will have to see what the ATs think. Definitively not a bad idea though!
