[UVB-76]

That sounds like a horrible relationship, and is certainly not the norm in many cities.

As a property owner, you should not have to request (by means of a "Post No Bills" message or other) that other people don't interfere with your property.

If it's not causing damage or vandalism then I don't quite see the issue. If the material is unwelcome then of course the property owner has every right to take it down. Mostly this ordinance is useful for closed / boarded up buildings, in my recollection.
