It Came From Beyond Midnight, a canceled public access TV show in which Spoony has a small role. He uploaded it in addition to his own content, only for it to increasingly come under fire by his fans for not being fully Spoony-related content because it bloated the front page of his website every time Spoony uploaded a new segment (seven videos per episode). He got mad about it and called out his fans on Twitter, saying his friends are more important than the opinions of the whiners.
Fans attacked his then-girlfriend after one appearance.
The above was likely due to backlash from the Mashable's "Funniest Person to Follow" award, which Spoony won. The celebratory video (which was deleted almost immediately) showed Scarlett draping an ermine cape around Noah. The joke went over everyone's heads and was interpreted as boasting. Among other posts were invitations for Noah to kill himself, fake posts from "Noah" himself claiming that his brother had died, etc.
Apparently Linkara and Noah have exchanged stories about the ridiculous Fan Dumb they've encountered whenever they do a cross-over.
Film Brain's collaboration with Spoony for the live-action Tekken movie led to his brief return for the DOA review, where Spoony's fans lay a medieval siege upon Film Brain's home.
It doesn't help when Fans have shown up at his house, in full costume no less, and have had to be removed by the police for refusing to leave. It's implied this has happened at his parents' house as well.
