I've been trying to find a link but i cant, maybe someone else will be able to.
Someone posted about being owed money and wanted to know if legally he could stand outside thier premises/home and wave a huge sign saying "bills not paid" or something like that anyway.
A few people came up with ideas on what to do or what they have done in the past, very funny to read and they got results from it as well.
Maybe you could try this approach of course not breaking the law. Embarrassment have have a great effect when it comes to other people knowing your business.
