Circle back to chaos
Unfavorable Semicircle
YouTube’s weirdest mystery channel is back in whispers — fans split on what it was
TLDR: A bizarre YouTube channel dumped endless cryptic videos, got terminated, then left hints via a resurfaced Twitter. Fans are split between “secret code art” and “glorified noise,” while Reddit and Discord keep the hunt alive—because the mystery now lives in the community, not the channel.
Remember that wild YouTube rabbit hole? Unfavorable Semicircle was the channel that flooded the site with tens of thousands of abstract, often silent or distorted videos—sometimes just seconds long, sometimes eleven hours—posted every two minutes. It got Reddit-famous, hit the news, then YouTube shut it down. The creator later nuked everything in 2017… and then a Twitter account reappeared linking to a “maybe real, maybe not” YouTube, pouring gasoline on the conspiracy fire. Now the community is the main character. On the subreddit and Discord, people argue whether the channel was a coded message, a social experiment, or just beautifully chaotic spam. The spiciest take? One user calls it proof that humans turn noise into religion, while another insists the creator actually replied on X, sending sleuths into full detective mode. The drama: “art project vs. ARG” (an online puzzle game), “mystery murdered by YouTube” vs. “termination proves it was junk,” and memes like the “cult of the semicircle” and “just two more minutes” every time a new clip dropped. With a community wiki and composite hunts, the vibe is part ghost story, part group therapy, and totally internet. The channel may be gone, but the obsession stayed—and the mystery keeps refreshing itself, just like those videos used to.
