> We all grow and hopefully learn from mistakes. ...An implication of this “banned users” data sharing is that this data exchange must be overseen by regulators

the gov't can require that each company has an appeals process, which can be brought to a court if the banned user decides that it's worth escalating.

In fact, i think a general, low cost court process for digital service providers would make for a great consumer protection, but still allow digital services to be flexible in how they want to provide. For example, google can still ban people, but the user can appeal, and if the user is unsatisfied with the appeal, they can go to court (without costing exorbitant amounts of money).
