As 'joniboini' has suggested you above, create a different thread either on
Games and rounds board or in the
Services board for running this campaign.
It does not look like a campaign to me. On games and rounds board you need to give btc reward and it must be a raffle type reward where nothing is guaranteed. On service board you will also need to pay btc reward. It's free spins offering and I do not think it's going to make much difference if they offer it here or create a new topic for it in the gambling section.
Everyone knows Nina Drama is the heart of our support team! 😉
Unfortunately I don't 😂
