I don't think you'll ever get rid of fake news. It's one of those things that's just gonna happen to a certain degree. It always has, always will.

You may be right that the platform will discourage it, but there's always bound to be some, and I don't think it's worth worrying about that much. I think the danger of fake news has been inaccurately perceived as being a pressing matter ever since the 2016 election due to Trump's popularization of the phrase to hate on CNN, which then got co-opted by the Democrats when they lost in order to blame fake news for their loss, when really it was just a excuse to avoid taking responsibility for the mistakes of the Clinton campaign and the corruption of the DNC during the primaries, which is what actually caused their loss. Fake news was inconsequential by comparison.

I certainly don't want to see Steemit become obsessed with cracking down on fake news the way that the corporate social media companies have. It's what led to the current censorship trend, after all. It's easily co-opted to be used as a weapon against news stories that the majority (or even just a powerful minority) simply disagree with or dislike. I don't think it's healthy for a community to embrace that kind of judgment. If there's fake news stories, then there's fake news stories. Stay informed, get your information from multiple sources, learn how to fact check and research, etc... and you'll be fine.
