It's flawed as well, all KYC-accounts are available for sale in many places, example Wise accounts, FB KYC verified accounts and so on, can buy by the thousands.

You can also just pay people to KYC (very easy) or do a "KYC Proxy with some DOM mirroring" with a fake service, ton of ways if you are a bit creative and have talent.

It does absolutely NOT prove that you are seeing human-made posts but incompetent users might believe so, I give them that.

Do share later as a post :)
