Welcome to CSR Nation
I would highly advise against NOT posting any names, although I think all of us should be able to have a COD list of reporters, agencies and even attorneys who are deadbeats.
I'm a reporter that lost a lot of money several years ago when THREE agency owners refused to pay me for the work I did. I took two to court, the other to a labor law group (who never collected a cent for me). At the point where I hit the THIRD agency, I quit reporting. I recently re-entered the profession and am now with good, reputable people who pay in 30 days.
However, to address your question, two of those agencies that stiffed me stiffed other reporters all over the country. Although we managed to find each other, some posted a blog and named names. They were promptly sued for slander by one of those agencies. The reporter was court ordered to take down the blog.
To be honest, I have a gripe with NCRA and my state reporting association for not being there for the small-time reporters. Those of us who are not agency owners and need to be paid because we don't have the cashflow agencies do. My daughter doesn't understand it when I say we can't go grocery shopping because so-and-so didn't send the check she was supposed to. I firmly believe that the dues I paid to NCRA and my state association should represent me as well as the reporting profession image. There should be some recourse in trying to collect money whether you're a reporter or a scopist. To not pay fo services rendered is theft of services and should be prosecuted in my opinion.
Long story short, if you name names (which I would LOVE TO DO), you risk slander litigation.
