Horizon Group Management has filed a lawsuit against , accusing her of defaming the company in May, when she tweeted about her former apartment.
Her tweet said: "Who said sleeping in a mouldy apartment was bad for you? Horizon realty thinks it is."
Horizon admitted that the Bonnen's apartment was one of several affected by an overnight leak in March, while a building contractor was making repairs, but said it had resolved all Bonnen's grievances and that she moved out on June 30.
The company's contention with Bonnen is that her post was published "throughout the world" which it claims severely damaged its reputation. It is suing her for $50,000 (£30,900) in damages.
However, Bonnen had only 17 followers at the time and her Twitter account has since been deleted.
Accordingly, critics of Horizon's actions have argued that by kicking off a lawsuit, Horizon has fanned the flames of publicity.
