First off, all these comments are from people or are they bots? I notice even on twitter when it comes to politics, you see these accounts post comments where it sounds like a bot... then you see other users who post the same exact thing.
I think it is possible that they are from a bot or if they are from people, I am sure, this message came from a group of people that are conspiring to entice readers in joining them. I have seen this kind of strategy on Facebook and youtube. They have templates of what they need to say with pictures and contact numbers. I bet this group of people is a member of a Ponzi company and wanted to recruit unsuspecting investors.
I assume the scam here is you then contact that persons whatsapp or phone or telegram, then they ask you for money... then you get scammed?
Or they will invite you to invest in a ponzi company promising a great returns.
