Hindenburg Research is shutting down 
What they did was mostly research companies committing crimes like fraud, release public reports and short sell those companies. They’ve also submitted whistle blower reports to the government. They were helping provide the capitalist rule of law.
Notably, the company only existed because a lawyer they couldn’t afford helped them early on. Otherwise they wouldn’t have been able to deal with 3 early lawsuits. If you point out that companies are breaking laws, they will sue you, and it will be hard for you to survive those bad faith lawsuits.
