To provide some context as to why that video might be being featured, in February, a vtuber named Pipkin Pippa
did a stream discussing Ralph, as well as Pantsu, who herself auditioned to be a vtuber once and posted that audition video online. During the stream, when Ralph was notified this was happening, he first tweeted that he didn't care what a cartoon rabbit was saying about him, then showed how much he didn't care by blocking Pippa's Twitter account. The point is that Pippa made fun of Ralph and that made her an enemy for life.
Fast forward to last week, when Pippa was doxxxxxxed. Some details were known before, but among those newly-discovered were that she is, or at least was, a fursuit-wearing furry, and that she "dated" a 20-year-old furry when she was 14, ten years ago, and is apparently still with him now (by "dating" I mean she identified him as her "mate" on a FurAffinity profile; we don't yet have evidence there was sexual contact before she was of age but it's pretty clear there was at least grooming). Ralph took this information from the Farms and did a stream laughing about how pathetic his enemy was, apparently not realizing a brainwashed grooming victim is still more pitiable than an obese drug-addled grooming perpetrator.
In the meantime, many Ralph followers have been resentful that the event has forced them to remember that anime and vtuber fans exist and have taken to the usual routine of calling us all losers and pedophiles and such.
