Yes, but iirc the suicide note doesn't claim that the KF thread was leading to ongoing direct harassment that motivated the (alleged) suicide. Just that the mere existence of the thread played a role. So we're back to "if someone has a KiwiFarms thread and kills themselves, then KiwiFarms is to blame".
If somebody writes about something in their suicide note, that easily clears the bar for "relevant for their decision making about their suicide" to me. What would the required evidence look like for you? Sworn testimony to a notary saying that it was KF and nothing else?
- Whether ongoing harassment from KF was relevant to their suicide
Unless one equates the mere existence to the thread itself with ongoing harassment then one can answer affirm the former question without the latter. The "required evidence" for the latter would require some sort of allegation that KF members were actively harassing Near at some point reasonably prior to their suicide, which afaik was just not alleged.
