The Steam Workshop section has seen its fair share of controversy regarding the mods that have been uploaded to the platform for a while now, ranging from game tweaks to cheat mods and scamming attempts. For this reason, Steam has now put a screening process into place, meaning that modders now have to await approval after submitting a creation.
The submissions now have to be approved by a moderator and you can read up on the matter here.
