KiwiFarms was literally started to harass trans people in general and Chris Chandler in particular (the name "KiwiFarms" is derived from the site's original name, "CWCki", a portmanteau of Chandler's initials and the word "wiki").
Kiwi Farms (whose name wasn’t coined until 2014) grew out of the groups who harassed Chris-chan in 2007 — but it’s obsessed with Chris-chan in way the original groups no longer are, and as a result its parent communities hold KF in (mostly mutual) disdain. KF’s first wiki, “the CWCki,” was created because users felt Chandler’s page on Encyclopedia Dramatica wasn’t detailed or accurate enough. Since 2008, every drawing, video blog, tweet, Facebook post, eBay listing, Etsy item, and PSN purchase Chandler makes has been archived on the CWCki and exhaustively discussed on the forums. During this time, various accounts of hers have been hacked, and the leaked data hosted on the CWCki. A whole coterie of KF members have also pretended to be Chandler’s friends and romantic partners in order to con Chandler into giving them more embarrassing content (photos, videos, drawings, etc.), which are then used to torment her. In the most extreme instance of this, they goaded a 13-year-old boy into masquerading as a 19-year-old girl in order to have phone sex with Chandler (and record it, of course).
It doesn’t just stay online, either. KFers show up in real life to document Chris-chan’s court appearances, to photograph the Chandlers’ residence from the street, or to surreptitiously photograph Chandler herself in public places. Over the course of eight years, they’ve contacted Chandler, her pastor, and her parents, posing as journalists, former classmates, psychiatrists, potential business partners, and others, in the hopes these ruses yield more confidential info.
Twice, female KFers arranged real-life dates with Chandler, both of whom used fake names and wore wires to record these outings. Packages and letters are routinely sent to Chandler’s residence, many of which contain obscene materials designed to unsettle the recipients. In one instance, someone sent prostitutes to visit Chandler’s house, then called the family to taunt them about it.
That article is from five years ago, long before the news of Chandler's sexually assaulting her mother came out. The Kiwis were so quick to find out and talk about it because they're obsessed with her and have been for the better part of two decades, and any Kiwi who says they're "indifferent" to trans people is a liar.
