If you're going to give people advice, you should be prepared to take at least partial responsibility for what happens when they take that advice.

If a lawyer, doctor, accountant, engineer, or any professional gives you bad or malicious advice, they expose themselves to liability for the results of it. If you want to present yourself as an expert on some topic and expect people to listen to you, put some skin in the game and stand behind what you say. If you can't do that, you shouldn't be advising people on anything.
