I have a very short (but useful) suggestion: change the KYC provider for testnet participants in Aptos.
The current KYC system (Persona provider) for AIT1 and AIT2 was very easy to abuse and people can use one document many times and get approved instantly. Because a lot of people abuse the system and it hurts decentralization which Aptos wants to achieve.
For example, a person using a passport can register it countless times and even a selfie for verification does not affect this in any way, the same selfie of yours on your document can be used a huge number of times.
So I suggest to change KYC Persona provider for other (Synaps for example). This will help Aptos avoid KYC abuse for the same document multiple times.
If the idea was interesting I will be very happy. And feel free to add your comments and questions.
