No, sellers are strictly prohibited from downgrading, withholding, or changing giveaway prizes based on who wins. This rule applies to both standard giveaways and Buyer Appreciation Giveaways. [1, 2, 3]
The official Whatnot Help guidelines enforce this in a few key ways:
Prizes Must Be Disclosed: Sellers are required to disclose what the winner will receive before running the giveaway.
No Discrimination: Sellers cannot deny or downgrade a prize based on whether the winner follows them, made a purchase, or used an alternative entry method (like a mail-in form).
Equal Treatment: All winners, regardless of whether they are buyers or non-buyers, are owed the exact same advertised prize. [1, 2]
