Terminology geekery: It would be cool if we could all agree to use a common language to describe this process, with appropriate signifiers. When a Referrer (Alice) refers something to a Referee (Bob). It would make life a lot easier. This is going to take some time though, because referral programs aren’t completely ubiquitous… yet. Also, because the term “referee” is most commonly used in sporting contexts. It’s not unimaginable, though, that the term “Referee” may eventually be accepted as a signifier of the person who’s being referred to a product or service. Time will tell. At ReferralCandy, we use the terms Advocate and Friend respectively– they’re not perfect, but they make sense and are easier to use.
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer", the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
