Well, given that the relentless harrassment has involved a massive amount of death and **** threats, genocide endorsements, disgusting **** and gore, extreme vandalism, and even child pornography, and that a police investigation will likely open soon, it seems like Fandom considers it as a less bad option to temporarily close the wiki from new accounts until they get information regarding what to do from the authorities.
However, I obviously do not like that innocent new members will not be able to join the wiki for the time being either.
