It started by letting her kids and animals run wild in my back yard. So, I dropped $5k on a 6' privacy fence that my father-in-law and I built. Then she had her water turned off for lack of payment and began pooping in plastic bags and throwing them over my fence. When confronted about it, she kindly denied and then took to social media. I called the landlord and had an eviction notice served the next day.
It's been 4 years and I kept the screen caps from her profile.
