This was in South Africa in the middle of nowhere. As soon as I saw that sticker (they put it on years after we moved there) I told my parents (I was a child at the time) it's time to move out, and they agreed as they also saw it after I pointed it out. From the beginning I thought the landlord was suspicious, but no one believed me. Tried to open a police case of racial discrimination against them but had no evidence so it went nowhere.
