What does "ploy" mean? In what circumstances could I use it?

Native speaker’s answer

A "ploy" is a plan or action intended to give a person, group or organization an advantage in a given situation. It has a slight implication of dishonesty. It can be best used when describing the activity of someone or something other than the speaker. Ex: He's been acting nicer to the boss lately. It's all a ploy to earn a promotion. Ex: Social media companies promising better privacy is just a ploy to improve their reputation.
