However, here is a list of bad neighbors you can be glad you don't have: The 7 Most Insane True Stories of Neighbors from Hell. In there we've got a lottery winner who liked to run a racetrack on his property and launch fireworks over the neighborhood causing a safety hazard, a woman living "in the center of a metropolis of shit-eating rats just to piss off a couple of old people", and a guy who framed his neighbor for murder for not helping him move a motorcycle.
What to do if you have terrible neighbors of any description? Well, if they see to be targeting you, you can start by sprinkling Peace Water around your property and laying pinches of Master Powder in the corners of your land (if your land isn't square or rectangular you can just guess where a corner would be -- just as long as you lay 4 pinches of powder.) If they gossip or are noisy, blowing or sprinkling some Shut Up Powder at their home may help. Another tested remedy -- with a rather good success rate in my experience -- is to freeze a problem. In this case you'd write the name of the neighbors 9x and place the paper, along with foottracks or any other useful concerns if available, into a jar or plastic bag which you fill about 2/3 full with water, then simply place in the back of the freezer never to be seen again. This 'freezes' the problem and makes it unable to continue to function.
If you hope to drive them away altogether, Black Salt, Black Water or Hot Foot Powder can be sprinkled at their property to cause them problems which will force them to move.
