On said Kiwi Farms, if you visit it, You have to solve a cryptogenic test with cloudflare, which sometimes goes down and BRAAAAPS! up the internet. Data miners can sometimes get h-ACK!-ed, and people can lose their money, data and more because of one little nigger janny stuffing hot pockets down his throat seethed at (You).
