Thank you for your concern. I agree with much of what you say. We are facing a global health crisis. The World is taking unprecedented steps to try and limit this.
We do moderate the forums actively and review EVERY post reported to us. So if there are specific posts you would like removed we will review them. We are not out to pre-screen content. We will remove posts that someone can show are factually false. Generally opinions or projections will not get deleted. But if you have a particular post email me
wejo@letsrun.com. Maybe I should just start a thread and have people link to specific posts they do not like.
We generally believe the best way to get somewhere is for their to be a discussion. If someone is uninformed in your opinion or does not understand compound growth rates properly, we generally think the best way to get somewhere is to allow discussion rather than pretend the other view does not exist.
You said, "commentary that diminishes the importance of this crisis is harmful to the public health. " Let's ignore the will be harmful to public health part for now. Defining "commentary that diminishes the importance of this crisis" is nearly an impossible standard. People are going to differ on what "diminishes the importance of this crisis" means.
Is a poster who says the worst case scenario by the NYTimes is way off base are they diminishing the importance of this crisis? What about a poster who says Germany shows how the situation will go in the US and the death rate is lower than many are projecting? Or is the NYTimes itself diminishing the importance of this because they wrote an article yesterday, "Some Ask a Taboo Question: Is America Overreacting to Coronavirus?"
You cite Bad Wiggins. Some of his projections have been way, way off base. Perhaps its easy to ban someone like him you would argue. Well I was looking at a thread from I think 5 days ago and a poster was saying Bad's projections were way off base. He/She then made a projection on # of cases that was more aggressive. Guess what? 5 days later this person's projections were already too LOW. Was their more aggressive prediction "diminishing the importance of this crisis" because it was proven to be off base? I would say no because they were saying we should take this more seriously but their numbers ended up being wrong.
But even if some posters are diminishing the importance of this crisis in your eyes, their views are not allowed to go unchallenged. Other posters can tell them why their beliefs or data is wrong and I think we get to a better more informed place because of this. Most people understand the nature of a forum and what is going on.
