I really like the urbex although unfortunately where I live there are not too many places to explore, however recently I found a fort from 1766 in a coastal city close to mine. All those rules you talk about are very important and valuable for this type of work, I don't understand why there are people who enter abandoned places to steal or vandalize, this is what alerts the nosy and makes them hostile to everyone , but if we maintain an altruistic attitude, no one has to be angry.
