YouTube has been claiming to fight disinformation campaigns in a policy it enacted this year.
However, a known common tactic of misinformation campaigns is to take truthful, but old, pieces of information and to present them as if they were new.
Some time ago, I noticed that #YouTube seems to have removed from its web interface any kind of information about when a video has been published. When did this happen? This can only contribute to the spread of misinformation.
