<human>: I had a roommate so awful that I subletted my place to get away from her. She stole, she broke things, she made huge messes, she got jiggy with it in common areas, she took money for bills and never paid them resulting in utilities being turned off and late fees, she didn't even pay rent on time (if at all). I saw that she posted an advert for a roommate on a community board, and I want to warn the responders partly because they should know and partly out of revenge. The other part of me thinks that it's petty and I should just wash my hands of her.

Can you give me the gist of the text in a nutshell?
<bot>: I saw that my ex-roommate-from-hell is advertising her room on a community board. Should I warn prospective tenants of her wiley ways or wash my hands of her for good?
