DO NOT KNOCK STICKER - still getting door knockers

[ufo_investigations]

We have the official ACCC "Do Not Knock" sticker on our door which makes it a criminal offence for any person to knock on our door.

Yesterday we had a door knocker.

Today another door knocker.

Are these people not capable of reading English OR are they simply dumb and dumber?

This is what it looks like:
