Lets be fair and steelman:
In Near's twitter thread he is nonspecific, stating that kiwifarms was "attacking and doxing my friends and trying to suicide bait [sic, suicide bait generally refers to pretending or threatening to commit suicide but I believe Near here means trying to drive someone to suicide] another, just to get a reaction from me. Null's email chain goes into a little more detail.
Near cited a few examples of harassment which happened offsite and blamed KF for them, all of which he gave dates for happened in 2020 and 2021 after his positive interactions with the thread. Strike 1- an anonymous user made a driveby post calling him a pedophile in discord. Strike 2- A friend of his was doxed on 4chan's /emugen/ board by a user claiming to be "from" KF, whatever that means, and that friend stopped associating with Near. Strike 3- Another friend of his was "almost" doxed "while they were suicidal" and again stopped associating with Near.
Though no dox appear in his thread and none of his friends are mentioned in it, Near claimed that he perceived these negative interactions to have begun or seriously increased in frequency and severity with the inception of the thread. Near's assertion was that he lived his life online and his e-friends are his only support network thus their loss was extremely affecting, and that he had a set of psychiatric disorders which made him highly sensitive to other people having negative opinions of him. This is what Near claims drove him to suicide and assuming any of these twitter trannies bothered to actually read his account, this is what they must believe.
