Follow the dispute

The challenge enters Kleros Court for jury voting. Submit evidence from the bottom of the profile page and monitor progress over 5-7 days. Appeal options are available if you disagree with the ruling.

Remove registered or Verified Human profiles

  1. Open the profile and click Revoke
  2. Lock a deposit (reimbursed if the removal succeeds)

Example evidence submissions:
  • Self-removal from the same address: name it “Self-removal of submission” and confirm your submitter status via the address.
  • Self-removal from a different address: name it “Self-removal of submission” and include a video recording stating: “I want to revoke my own submission from the Proof of Humanity registry”.
  • Malicious submission removal: name it “Removal of deepfake submission” and include deepfake analysis reports as evidence.

Remove in-review profiles

Use the challenge process described above.

​
Resubmit a Profile

From a new address

  1. Ensure the old profile shows Revoked status (check https://v2.poh.id/PoHID)
  2. Remove it if necessary using the steps above
  3. Connect the new address and submit a fresh profile

​
From the same address

  1. Verify the old profile is Revoked
  2. Remove it if needed
  3. Click the Resubmit Profile button at the bottom left of the profile

​
Reapply an expired or expiring profile

Profiles expire two years after registration. Reapply to prove your continued existence and control of the address.
