They know enough to be reading HN (for a good while now) and making a stock market game. I don't expect them to know the details of securities laws, but I do expect to know that there are some laws about that sort of thing which they should look up or ask someone about, because that's just basic common sense that you'd know if you were interested in stocks in the first place. Plus, every sort of contest or public entertainment website or write-in competition has a bunch of fine print that says things like 'For entertainment only, not valid in every state etc. etc.' I've been aware of those disclaimers since I was , I dunno, 8 or 10. You don't have to be a securities lawyer to figure out that they're there for a reason and that there must be some rules in each state about how you conduct such activities.
They got an idea and spun it up in a weekend.
They ran it over a few months, publicized it, and demonstrated their knowledge of brokerage history history. Plus just about every 'How to set up a small business' guide ever written warns about setting up a structure to protect yourself such and LLC or the like.
But bureaucrats are basically sycophants and / or bullies. They aren't in the job to protect the public. They're in the job to make money by connections, and to push around people without the knowledge or stones to tell them to fuck off.
Yes, everyone is exactly the same. They're all big old killjoys who don't want you to have any fun man.
Grow up.
