Thanks for the warning. Black Regions are dangerous and full of crime.

They also had this strange structure, maybe for cheesing animals? (sorry couldnt attach due to file size)

this isnt to cheese animals, this is a airlock for milestones, since their path cross cliffs you can abuse that to even make safe airlocks for park ur knarrs/snekks since u can block and unblock the path from insife whenever you want to use it.

can the cliff not be destroyed?

You can test it and report here. No need for pali, just pave on both sides of the cliff like in the picture and see if you can do anything to it.
(There is literally no point that you can dig or have it absorb dirt, so my bet is on "No".)
