I thought about this a lot. Initially, I wanted phone authentication, but decided to do that next time when the problem arises. Then I realised that the goal of this is long term investing, I.e. 3-5-10 years. I doubt these “return miners” can do so over the long term while writing good insightful posts on their positions to build enough reputation to thrive on the platform.

But then again, it’s still possible to maintain two to three accounts running different strategies. And so moving forward, I’d either try phone auth or Stripe’s identity verification.
