There is a french website that did offer checks to know if your news website was a source of good, poor, or straightup lying articles, wether you had to check up twice the information or if it was a valuable source.
Some examples of poorly rated newsites:
-Dailymail:
Be cautious and cross with other sources. If possible, go back to the origin of the information.
-Foxnews:
Be cautious and cross with other sources. If possible, go back to the origin of the information.
-Breitbart:
Be cautious and cross with other sources. If possible, go back to the origin of the information.
