There will always be FUD when innovation meets money, and that is what crypto is all about.
Censoring it does not provide a solution, but makes things worse, because in the end there will be more FUD the more posts are deleted, trust gets lost and the community gets anaemic. That is exactly what can be observed in this thread in the last year.
In fact most users (including the silent majority) is very well able to distinguish between FUD and constructive critisism. But where open discussions can take place, a strong community may thrive and have self-cleaning effects when it comes to FUD and doxing.
In some cases it might be necessary to block users, who want to attack/destroy a community by persistent trolling, but this should happen in a transparent manner, e.g. by posting a screenshot of the post that caused the ban, and giving a plausible reason for it.
