 If we accept Mill's argument we need to ask “what types of speech, if any, cause harm?” Once we can answer this question, we have found the appropriate limits to free expression. The example Mill uses is in reference to corn dealers: he suggests that it is acceptable to claim that corn dealers starve the poor if such a view is expressed in print. It is not acceptable to make such statements to an angry mob, ready to explode, that has gathered outside the house of the corn dealer. The difference between the two is that the latter is an expression “such as to constitute…a positive instigation to some mischievous act,” (1978, 53), namely, to place the rights, and possibly the life, of the corn dealer in danger. As Daniel Jacobson (2000) notes, it is important to remember that Mill will not sanction limits to free speech simply because someone is harmed. For example, the corn dealer may suffer severe financial hardship if he is accused of starving the poor. Mill distinguishes between legitimate and illegitimate harm, and it is only when speech causes a direct and clear violation of rights that it can be limited. The fact that Mill does not count accusations of starving the poor as causing illegitimate harm to the rights of corn dealers suggests he wished to apply the harm principle sparingly. Other examples where the harm principle may apply include libel laws, blackmail, advertising blatant untruths about commercial products, advertising dangerous products to children (e.g. cigarettes), and securing truth in contracts. In most of these cases, it is possible to show that harm can be caused and that rights can be violated.
