If the prizes are Scratch social actions then it is going against this policy here:

It is not okay to use Scratch social actions such as likes, favorites, or follows as a form of payment. Scratch social actions should always be something that Scratchers give freely, not something they do because they are getting “paid” for it.

Please feel free to link them to this post or the policy.
