I think this is a fair criticism, but in all honesty a determined attacker would probably have better vectors both in terms of companies to trade against and in terms of people with access to actionable information.

Also worth noting there have been times I've thought the price should go up and it went down, and vice versa. While I have a good view into financials (and believe I would have made money insider trading, on the whole), it's not complete enough to warrant something like threats, blackmail, etc.

Being tempted and acting on those temptations are two different things. There is nothing damning in this comment. I appreciate the author's honesty.

I have no reasons to imply that the commenter would be tempted or acted at all. But there are means of coercion other than money.

I admit though, I watched too many spy movies and TV shows

I think you gave good advice. If someone has privileged access/info, they shouldn't advertise it to the world. It's just asking for trouble.

Wouldn’t someone determined just look at LinkedIn?
