I can tell you ‘about’ something that would. For instance, I would get banned for doxing you. The reason why I would get banned is that the information would be very valuable to someone that the forum is not interested in helping. Some banned conversation includes realities that explain what is going on in the world in a way that can greatly benefit a potential investor, or equivalently, greatly misguide them. Given that there is no way to discern between the two, both are banned.
I have one personal example that I am willing to share. I learned a tremendous amount of helpful information about birth practices and infant care from one of these ‘extreme free speech’ platforms. An example is cord clamping. The debate of this topic was extremely irreverent and ad-hominem, but it was easy to see that logic and objective results clearly favored one side, regardless of the civility with which this information was presented. Sadly, I don’t believe the information would have been effectively communicated in its most polite form, because it was clearly out there for all to see for a very long time without any improvement to common practice. The problem is that a reasonable person must ask why experts would ignore such information before accepting alternative possibilities, and this necessarily leads to a very dark rabbit-hole showing politically-incorrect evidence of extreme dysfunction within their profession. This became broadly applicable to me personally. My OB/GYN was objectively harmful to my baby, my pediatrician and nurses were wonderful, and this was all much less confusing given that understanding.
