In his latest post he encourages other bloggers to blog about scammers. He's right, and I've blogged about scammers for years. If you Google CBCS Collections, for example, you'll find my blog.
Also, if you Google the name of unethical scum bag prosecutors, you'll find my blog, too.
It's not possible to right every wrong, but it is possible to prevent others from suffering future harm. In that sense, my blogging has always been a form of public service.
