Neighbours have received fines of up to £25,000 for knocking on a homeowner’s door after he accused them of trespassing.
The man, who lives alone at his £300,000 three-bedroom terraced home in Bristol, put a notice outside his property stressing he does not want any unannounced knocks.
It also bans people from sending him junk mail.
The Bristolian included the measures in his plan to introduce new privacy and security measures.

A tall wooden fence has also been erected outside the property, with the front letterbox blocked up and a large black post box attached for legitimate mail.
The notice warns passing charity fundraisers, political canvassers, delivery drivers and neighbours a warning there will be consequences for stepping into the small front porch and knocking on the door.
Entry is instead “by invitation only” and "trespass and damages fees apply".
The notice added: "Implied rights to access permissions removed. To all persons corporations councils and agents thereof. Vehicles manned or remotely operated.

"Per person or per vehicle per offence including vehicles either manned or remotely operated."
The Troy ounce fine is worth the equivalent to £27,360.
The notices references case law established in New South Wales in Australia.
It concluded: “This means you are bound and agree to this contract by entering uninvited, whether you think so or not - applies to you whether you think so or not. ID to be surrendered for inspection.”
Despite the situation, neighbours appear supportive of the resident.

A woman told The Sun: “He is a troubled individual but means no harm.”
A man added: "He's a bit of an eccentric and gets annoyed with people knocking on his door unannounced.
"He also has a problem with junk mail and that's why he put the sign up outside his house.
"He is very intelligent and you can see by the way that he has researched the law that he genuinely believes he is in the right.
"I don't know whether what he is saying is enforceable but he obviously believes it to be and that's why he put it up."
