Should Similar Worlds take its cue from Facebook with regards to intentional misinformation?

I speak specifically with regards to COVID-19. I do not care if others choose to support the lie that the election was rigged. That is a political debate, not a health hazard. However, there are those who choose to perpetuate lies that will allow COVID-19 to proliferate and mutate in the bodies of the gullible for years to come, should they follow the advice of certain users. Does that not constitute a risk to the lives of the general public? I consider it to be even worse than shouting "Fire!" in a crowded theater.
