The posting requirements is against the rule of this forum for it is encouraging spamming and will cause the moderators to delete this thread, that requirement is not needed in an airdrop which usually came with some small task like following at twitter, joining telegram etc...
Those posts are not spammy and stretched during month. In fact, each person is advised to post max 2 during day.
Plus, this thread is not about Airdrop only. It is meant for the limited Token Sale as well.
