Already listed this among necessary stuff to be developed for our community... unfortunately I lack the skills to develop it. I believe someone must have thought of the idea long ago. Hopefully the concept is developed by this someone or some other person. Secure crypto forum/community will be free of corruption and dishonesty.
So everyone will be required to register with his/her fingerprints, iris, or face. Biometric Data cannot be copied or held outside of the Blockchain.
When admin suspects foul play he could ask his "suspect" to permit Forum software to link up with his "Blockchain Biometric D" Account so scan can be run to prove his/her innocence. Unfortunately, scan can't work without the suspect's permission, for the sake of Anonymity. If suspect refuses, then that would be more reason to suspect him/her. If he accepts then forum will link up with his Biometric Data at the Blockchain website, he will click accept & scan will be ran quickly. His data won't be known by forum. Only the blockchain will know his data and only it can confirm whether suspect has multiple accounts or not.
The Blockchain will have the Biometric data of all Forum members for things to work 100%.
Countries can tap into this technology to avoid having a centralized Biometric Data stores. Security agencies can solve crimes with it too.
