I'm not sure but I think many here are not fully understanding the article. It is not saying that people should be banned from chess based on accusations alone, though temporarily barring them from events while an investigation is underway if they have received multiple reports against them sounds more reasonable.
The issue was that these organizations did not have a timely response to the accusations and offered no protections to those who made those reports. So even if we can't be sure if an accusation is true/false, one can still provide protection to the accuser, and take their claims seriously and investigate them more urgently than they were.
I was about to post in agreement with
@Pashut and others that we shouldn't be banning people based on accusations alone. But if you carefully read the article, it is really talking about something completely different than what people in the comment section are discussing.
Ironically I also dislike social justice as in many cases I think it goes way too far, but in this case there is nothing to be upset about
