Options are already broken into levels 1-4 (this is an industry thing, not just RH). Levels 1 and 2 don't run the risk of this happening since you can only sell to close. On other platforms that I've used, going from levels 2 to 3 took a while and required some verification steps to try to confirm that I knew what I was doing.

Robinhood already asks for information about your net-worth, income, etc. The problem is that they verify nothing (at least in my experience). I read /r/wallstreetbets all the time, and plenty of 18 year olds say they are making 100k+ and RH just approves them. They need to improve that process.
