Guy I new lived in a community that was building out.
An allegedly "allergic to everything" woman moved in, and within a month started laying down demands, followed by lawsuit after lawsuit, mainly on materials that were being used to construct the new houses nearly half a mile away. Various lawsuits demanded specialized building materials, that the houses be built without (and rented/sold with riders forbidding) anything but all-natural-fiber carpets, paints, whole 9 yards of wackiness.
Then she started suing her neighbors over cooking smells, cleaning products, their pets, demanding incredible accommodations. She would also leave notes on people's cars about how they were "murdering" her with the fumes and threatening to make everyone buy electric cars. She sued over people smoking in their homes, demanding that the community be deemed a complete no smoking zone. She sued over satellite dishes, saying they aggravated her condition.
The community tried to be accommodating, but every time they tried to meet her half way she upped the demands. She made life hell for everyone for about 18 months and cost the community and her neighbors a lot of money.
Then one of her other neighbors filmed her in her back yard one afternoon (guess she thought everyone was at work)....
Smoking several cigarettes.
Things went a lot less well for her after that, she was hit with a bunch of counter suits, and she eventually moved.
