We don't need a new law. The schemers can be fired and rules can be written to guard against it.
what do you think a rule to guard against it is - in my world that's a law.
What do you think should it regulate that currently isn't?
Perhaps we should be regulating marketing? It clearly doesn't serve the public interest to allow micro-targeting at this level, particularly in political situations.
sorry didn't answer earlier, on vacation - but I don't think there is a provision that allows a company to sell access to profiles that end up micro targeting 1 individual or maybe a provision saying no sell of advertising can be written to target less than 100 people, only people employed by one employer, or in one location - location described as (some description that keeps you from targeting everyone in a particular building.)
