The SEC definitely targets sudden, surprising stock moves, and looks for people who profited off them. (This is why one of Matt Levine's tongue-in-cheek 'rules for insider trading- this is not legal advice!' is never do it in short dated, out-of-the-money options!) I'm sure there are relatively sophisticated ways to exploit the market that the SEC probably won't catch (that are also more sophisticated than I understand), but now you need to have a sophisticated understanding of the market, and of cybersecurity fraud (to beat Twitters payments verification), and naturally maintain flawless opsec on both throughout. Harder and harder to do.
