Growing up, my teachers/mentors taught me not to cite Wikipedia directly for any academic/journalistic works, mainly because most people didn't actually check the sources that article writers were using and there's the risk that there's heavy biases one way or the other because - anybody can edit articles.

Looking at the Wikipedia article you linked, I don't see any definitive, authoritative sources of information that directly links KiwiFarms and these horrible events other than random tweets posted by people on the internet.

After looking through 5-6 different sources cited in the bottom of the article, I don't even see any references or screenshots of the actual website used in reporting, just journalists taking what other people are saying as fact.
