As far as I am aware, there was some drama with a trans activist/online personality who didn't like KiwiFarms. I have heard that there was some foul play with false flags about swatting, doxxing, and other alleged lethal threats against this person originating from KiwiFarms, but I don't know what the truth really is. Anyway, that's how the campaign to take the website down got started. If I recall correctly, the activist goes by the username of "keffals". I only have the most surface level information on this, so if you put any basic research of your own into this matter, you will probably know a lot more than I do.

I suppose this is just another example of the apparent nigh omnipotence of trans activists on the internet. I wonder if they would succeed in deplatforming Rowling if they really tried their hardest.
