I agree with the fact that the Internet needs a kind of reputation system. That is why Web 3.0 such as hive owns the future.
Most of the times, it's not that people can't discern fake information from true ones. The psychological effects of the fake info just seem to linger. You are quite certain that your headache is not tumor related but your mind will keep going back, what if its tumor? 😅
That is the power of information. You would have already finished the diagnosis on your body with information on the Internet even before the real diagnosis is done. Many people have imagined sickness that is not present in their body just by fake information.
