I only know about the guy due to his repeated spergings in the livechats of various IBS related shows. His incoherence is sort of fascinating to me. He also seemed oddly content to yell to the world that in addition to really liking turtles he is a divorced alcoholic who doesn't get to see his kids. When I was having trouble coming up with a name for my Kiwi Farms account I thought about how people have Chris-Chan related accounts. I figured why not do something similar with an obviously exceptional individual who fascinates me personally. I didn't know that the rabbit hole goes deeper on him and I also didn't know that other people new about his existence either. But yeah, it doesn't surprise me that in Ralph's fan server he has a shit brown role.
In addition to wanting to annoy him if he finds this account, I thought using the discworld turtle really kind of works as an avatar.
