Guerrilla marketing carries a risk that traditional campaigns don’t — because the entire approach relies on provoking a strong public reaction to a cheap, unexpected stunt tied to a company or its offerings, there is no way to guarantee whether that reaction will be admiration or backlash, and a tactic that offends instead of delights can damage a reputation faster than any paid campaign could have built it. It also limits control over how the message is interpreted, as people may misunderstand the idea or associate it with negative intent. It further creates legal or public space concerns, where unplanned setups in shared environments can lead to complaints, penalties, or forced removal.
