When an HOA works for you, I agree. Most of the are extortionistic busybodies that charge you money for the privilege of informing you that you cannot install a brass kickplate on your door, or that you can only have two vehicles or some other bullshit.
We've got a thread on Nextdoor going on about three houses that may or may not be abandoned on a specific street, and their yards look like hell- what can be done? Every year it's the same. One year, the home owner turned out to be an elderly invalid, so the neighbors got together and worked a rotating schedule for lawn care for him.

There are times when Nextdoor's power can be used for good.
Then there are other times when it provides the Hatfields and the McCoys more ammo for continued warfare...
