Crazy idea to help stop the spreading of untruthful news

One of the main issues with news on social media is the spread of fake or false news. This happens on every platform that allows sharing news. If Tildes continues to gain popularity, this will likely happen on Tildes. I had an Idea: what if tildes had a group of fact checkers that check to see if the news is truthful, and block posts that link to untrustworthy new sites? could be like a 3 strikes thing, where if a new source has 3 articles posted that have misinformation, they would be blocked (the post also removed).

This is just an idea, feel free to highlight any issues with it.
