You’re misunderstanding the process.
It goes something like this (it varies by country / citizenship): first you upload a picture of your ID, then you use your phone to take a video of your face, then the two are matched. A failure is when the uploaded ID doesn’t match your face.
You can’t get to the part where they don’t match without uploading a picture of their ID. If you don’t have their ID, then you can’t fail to match. If you fake the ID, then when they come to upload their own ID, their ID won’t match your fake ID and they won’t be blocked.
