It doesn't even matter. Harassment isn't like blackmail, the things you are harassed about don't need to be true, it just has to be inconvenient. For example, if hundreds of people call you at every hour of the day and the night to say "We know what you did", you don't even need to have done anything wrong, the harassment itself can still get to you.

The document states that Near was able to withstand the harassment targeted at themselves, but that it became harder for them once Kiwi Farms targeted their friends. They isolated them from their friends, and that apparently was enough to push them over the edge, as it would for many people.

I don't believe this was about anything specific.
