This kind of system would render a totally inaccurate result. If people's votes all weigh the same then people who just wants to promote fake news and make it "credible" based on votes would really benefit from this system or they could also make real news "fake" if it will also be favorable to them. If you want a more accurate way of voting or screening the news if it is real or fake I would suggest that you have a weighing system or credibility system that gives credible users have a bigger weight on voting. This system can be achieved based on voting accuracy, credibility of the user, or even if the user is based on the country where the news is from and he has additional local information in hand he can be more credible and add more weight in the voting system.
