@Saftzie clearly you don't understand the security issue that exists currently. This is a wiki farm, these wikis are all connected. Staff decided to allow local admins to edit user JS, that was a bad decision considering that there are rogue and mean people; thankfully not many were able to abuse that tool.

Staff is still working on the review processes and in all seriousness while CSS most likely won't be reviewed, JS will be and that should include anything that is JS.
