My neighbors (Maryland) have had a broken down car in front of their house for 2 years now. I see HOA violation notices on it every once in a while threatening to get it towed if they don't fix it, but nothing ever comes of it.
And every year we see news stories of HOAs inducing foreclosures etc on owners for $10 late dues, flying national flag, or painting a porch the wrong shade of white.
Gov't/HOA involvement & enforcement varies wildly. This subthread regards those thinking "1984" was a good idea.
