The Hanging Head might not be such a law abiding business but it still something that is not entirely evil.
They usually give warning and persuade people who could not afford to buy the information not to buy anything.
If you don't want to buy information, you could simply come to the Hanging Head and drink your sorrows away.
For all the bad rep it got, most of the fault lies in the buyer.
After all, if people got the information and not pay, what face and reputation would be left for the Hanging Head tavern?
They had to take actions.
And most of the time, the actions taken against buyers who could fulfil the other side of the deal is very brutal.
Because in the crime world, if you do not do such a thing people would be thinking that you got soft.
And the moment you let people think that you are getting soft, then hyenas would began circling.
