1. The age verified badge shows that you're an adult. On the other side, unverified user is showing that they're "potentially minor". Imagine, if you're a predator, why not targeting unverified users? why not pushing adults age gated instances, narrowing targets?
  2. Current Persona method isn't looking good for privacy reasons.
First, it says "Age Verification", but in the process, you have to submit your ID and face, which is obviously too much information. At this point, the verification here possibly is ID verification. Quite misleading.
Second, how do you know if your data is still stored in Persona? You hand your ID them blindly trust Persona, which you can never control once your data is breached from them.
