Brewer always gets stick for being a bit of an ass on that TV show. I just take it with a pinch of salt, and sometimes - might pick up a few tips and tricks - but mostly its just entertainment.
Why have you assumed its her fault and not theirs? If she hadn't given the home address I would ignore it and tell em to F off. As the family home is potentially at risk and judging by their behaviour, I can only, sadly, imagine they would go as far as damaging property - I'd try getting them to either sort it out themselves, pay half of it - or go through insurance so they don't think they've won.
