AssMod Question

On an old server I used to have I fixed a problem that allowed players that have previously been banned to noclip. It was like the permission below Guest and I had to reset it everytime. Is there a way to make it so they automatically get set back to guest or at least stop them from using noclip? Noclip is already restricted to everyone except admins.

I am pretty sure I just changed something in a assmod file somewhere but I don’t remember where or what I changed.
