A lot of Bernds don't want to stay on a board which allows and promotes pedoshit. Such a board risks getting displatformed at any time, and puts honest Bernds at risk with respect to law enforcement.
Before this incident it was kind of unclear wether the mods were just negligent, or had an extreme-libertarian view (any content should be allowed !), or wether they really were pedos themselves. Now all doubt has been lifted, and the more sensible Bernds don't want to continue posting on a board run by such people.
