Irritated by your neighbours taste in music? Think that buddleia bush might be straying into your garden? In the pre-wi-fi age, your only recourse was to have it out face-to-face, or perhaps send a strongly worded letter to the council.

Some of the mischievous monikers mentioned in this BBC News magazine include
"Stop Stealing My Paper!"
"Shut the Barking Dog up No 7"
"We Can Hear You Having Sex"
