Eviction over a Facebook review?

[Dovid Staples]

Hello BP. My lady is a living in an apartment complex in Chandler AZ. The management is terrible and I hear about one issue after another after another. The laziness of the place bugged me as well as I visited often enough. Since she doesn't have a Facebook I decided to leave a negative but truthful review on their Facebook page.
They had the audacity to actually call her in to the office and demand I take down the comment. They said they would charge her an extra $75 a month as if I was a resident and even mentioned things about eviction.  

Real or empty threats?
