Hi. If you find a campaign that does not follow their rules when to give airdrop, then maybe you should think twice if you continue to that project or find a better one. As far as I know, when the manager said that the airdrop will be given this coming saturday or friday, then expect to receive airdrop. Sometimes the distribution are delay but not too long as long as 1day delay or 2days maximum is acceptable exceeding of that is questionable.
