And the unwritten/unknown rules of how to do skirt around the law aren't going to be changed by this situation. We still (in my opinion, unfortunately) have a legal system that is way to heavy on "word of the law" vs "intent of the law".
We saw some of this a couple weeks ago. True intent is hard to prove through words, and context is super important.
For what it's worth, I seriously doubt that someone on reddit who made an market-manipulation-incriminating statement and made a couple hundred bucks will face punishment. I suspect that when all of this is looked at at the end, the "gains" will be rather bi/tri-modal. A ton of people losing money, a bunch making a little bit (relatively), and then a small handful who make absolute bank. The group on the right are the ones who will have to be careful/worried.
I suppose my point is that someone with intent can use careful language to avoid creating any evidence of intent (and lawyers will cheer them on) and then someone without much in the way intent will say something sloppy that implies intent (and lawyers will punish them severely).
