I linked NHK, basically the Japanese news source that also publishes in English. However, if you want a lot more context from the case, you can read the Crunchyroll article here that has a lot of background for the case.
I understand trying to get ahead of something that you think might turn toxic or veer off into realms in which heavy moderator action might need to be taken (that is basically what I did after the recent issues with the ml instance). However, trying to cast this case as not relevant to the topic of anime is a pretty strange view to take considering the lasting effects this event has had on the medium for years.
