I know someone who moved in with someone on Craigslist and they turned out to be a tweaker and was creating drugs under their roof.

My best friends moved in with someone they found on Craigslist who turned out to be mentally ill who wouldn't take her medications and was accusing them of stealing and breaking her things, she was stealing their things, she was constantly harassing them and trying to start fights with them so she could call the cops on them.

And this was in my area, not the big city. The big city is where thing get really shady.
