I'd like to hear more about this.

Someone reached out via my Hacker News "who wants to be hired" comment offering a job. We did interviews, I got hired, onboarded and introduced to the team. They missed meetings and then disappeared before the first discussed paydate, ghosting me. They were set up in every way to do this. It seemed to be their standard M.O.

How do they profit from this?

I don't know if "profit" is the right word as it implies customers, but I guess they rip off devs and crypto investors they enter into contracts with then run away from, misappropriating investors' money and not delivering any value. The devs just help make it seem legitimate. There is no actual value creation involved.
