I doubt they’ll even be able to trace the original account that created the .rbxl to ban it. Also, they definitely won’t. There’s been some nasty .rbxl files roaming around exploit forums and they’re still up for download and local use. Roblox can’t do anything about that, as long as you don’t publish it.

it is not necessary to publish the code for everyone, it will download even those that are hidden. ^-^
