This basically answers your question. They are following the herd.
Majority of them don't bother with research, all they see are huge crowds on chatrooms, mega-hype on forums, memes on social-media etc.
There is also language barrier, lack of experience and to much of extra money.
Person referred as Jesus on the telegram chat called followers "his bitches" in the official announcement of the airdrop.
And this wasn't a joke, at least there was nothing that indicated a joke. Just like that he lost probably a few people and even one of his minions, referred as Jesus's Donkey, felt a little resented(I assume) and retaliated him with F.U etc... lame and boring shitcoin.
