Sponsorship requests only appear in AdCollab once they are “officially booked”. By this point you - the creator - will have been asked whether you wish to take the sponsorship by whoever at Acast is managing the campaign. If you have any issues around the suitability of the campaign for your show, please contact your Acast representative.
In the long term, we may expand AdCollab to allow creators to handle the “approval” process from within the product - when that happens we will of course let you know.
