However, it might be bots that don't care about legitimacy of project.
They are not bot maybe. But the works proves they are human bot because they don't know what they are promoting and there have any chance to get paid by them or not. They just can visit some airdrop listing sites and when they see a high reward airdrop is listed then they start blindly promoting them. Don't care to investigate a little bit even atleast for own self.
These fake project are increasing day by day because of the social media promotion. If there is any way of catching or marking scam project then its can not raise more Imo.
