This site is great to vent but you should really sit down and read this thread from begining to end.
To sum things up, you have dead beat neighbors who have for a long time taken advantage of you. You ignored their ungratefulness, bad behavior, and even cheating you. Finally, you put your foot down when they stole firewood from you.
Putting your foot down has cost you:
a lot of work
over $1000.00 in surveillance equipment, surveying, lighting
In the near future you will have to spend more money on permits and fencing
and what is the payout for your investment?
you have legal problems with dead beat neighbors and you might end up having to get a lawyer and going through God only knows what.
People who are this lazy would rather spend countless hours figuring out a way of pinning their troubles on someone else rather than taking five minutes to accept responsibility and repair the damage they caused. People like this will blame you for every bad thing they ever did to you; they think you had it coming.
Knowing this you are openly getting into a peeing match with people with nothing to lose and who's ruthlessness is far beyond your pay grade. Do you really think it is wise to post your prank/revenge ideas in a public place where they can find them?
My friend, I think you need to revisit your strategy. Stop fighting them with your pocket book and at the very least get rid of any post that could be viewed as libelous.
