When you have to set a proof for a new mission you face with a dilemma: show it publicly or not?
The answer is easy but only if before you ask yourself another question: is the submitted content you’re asking to the fan a UGC or not?
If yes – such as selfie, picture took at an event, etc. – the proof should be shown publicly: this will increase the social activity in the community, by stimulating likes and comments on that specific user generated content, that automatically is shown in the community news feed.
If not – such as confirmation email for a payment, screenshots of the invites the fan has done on the socials, etc.- the proof shouldn’t be shown publicly: there is the risk of disclosure of sensitive information about the user.
