I had to look up what kiwi farms is -- a site used to harass people. Saying she belongs there seriously undermines your credibility. And what's a "classic cow"? Is that just a pejorative for some type of woman?
kiwifarms is a forum where people laugh at other people usually internet famous people that make a fool of themselves on the internet. The rule is that you don't interact with the subject. There are a lot of people visiting the site and you can't control what everyone is doing but from the few threads that I have watch I did not see any call to harass or interact in any way with the subject.
Before posting a comment you see the forum guidelines that includes: "No trolling plans. We are not an autistic Illuminati. If you embarrass yourself or the forum trying to troll, we will ridicule you."
The subject of laughter is called a "cow" because it provides laughter i.e. "milk" through his/her action on the internet. The term cow is used regardless of gender, sex, age, etc.
