[0:07](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=7) That first day, that channel uploaded one thousand two hundred and forty-seven videos within twenty-four hours. [0:14](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=14) The first was titled The Sagittarius Symbol, followed by nine eight zero seven zero eight. [0:20](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=20) It was four seconds long, a brown background, no sound. [0:24](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=24) Then another video appeared, and another, and another. [0:28](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=28) The channel uploaded a video every few minutes, then every few seconds. [0:32](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=32) Within nine months, it posted over seventy-two thousand videos. [0:35](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=35) No human could do that. The Internet noticed. [0:39](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=39) They thought it was a bot or a glitch. Then they started combining the videos. [0:43](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=43) Thousands of frames assembled into composites. [0:46](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=46) An image appeared. A man in what looked like a suit, but he had no face. [0:52](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=52) His face wasn't blurred. It wasn't there, like someone had erased it from reality. [0:58](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=58) To understand how strange Unfavorable Semicircle was, you need to understand the scale. [1:04](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=64) YouTube's upload system has limits: verification, processing, compression. [1:08](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=68) Each video takes time. Now, a dedicated creator might upload one video per day. Ugh. [1:14](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=74) A prolific channel might manage ten or more per week. [1:17](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=77) Unfavorable Semicircle started at one video every ten minutes around the clock. [1:22](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=82) Then it accelerated. By February 5th, 2016, the rate hit three videos per minute. [1:28](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=88) No breaks, no pauses for months. YouTube's infrastructure in 2015 wasn't built for this. [1:34](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=94) They limited creators to ten to fifteen uploads a day unless you had a special agreement. [1:39](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=99) Even verified channels with dedicated upload pipelines couldn't sustain more than fifty videos a day. [1:45](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=105) So three per minute? That required direct server access, back-end permissions that shouldn't exist. [1:52](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=112) And the content made no sense. Each video was different, but they followed patterns: abstract shapes, flickering colors, bursts of static. [2:01](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=121) Some were four seconds long, some lasted hours. [2:04](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=124) The longest ran eleven hours. Some were completely silent. [2:08](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=128) Others contained high-pitched screeching that made your ears hurt. [2:11](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=131) The visuals looked like test patterns from a television station: pixels arranged in grids, geometric shapes that pulsed and shifted, colors that flashed so rapidly they triggered headaches. [2:23](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=143) Some viewers reported nausea, disorientation. [2:26](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=146) One Reddit user said he watched for three hours and lost track of time. [2:30](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=150) When he checked the clock, six hours had passed. [2:33](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=153) Another reported ringing in his ears that lasted for days. [2:37](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=157) And the titles were equally strange. Numbers, mostly. [2:40](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=160) One eight six zero zero nine eight four seven. [2:44](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=164) But sometimes symbols appeared. The Sagittarius symbol, followed by the word Delog. [2:50](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=170) Sagittarius, brother. Sagittarius, brill. [2:54](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=174) The Sagittarius symbol showed up constantly. [2:57](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=177) And it wasn't typed. It was hand-drawn, each one slightly different, like someone sketched it frame by frame thousands of times. [3:06](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=186) That kind of repetition meant this was intentional. [3:09](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=189) The channel flew under the radar for months. [3:12](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=192) Then in November 2015, someone on Reddit posted, "Found something weird." [3:17](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=197) The thread had three responses. By December, it had two hundred. [3:20](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=200) People built databases, wrote scripts to download and analyze every video. [3:25](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=205) They used spectrograms to visualize audio, custom Python scripts to extract frames. [3:30](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=210) One user built a database tracking every upload timestamp, looking for patterns in the intervals. [3:36](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=216) By December, the investigation had its own subreddit with detailed documentation of every discovery. [3:42](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=222) Reddit user Jackalackadingdong, that was his handle, he spent months on the audio files. [3:49](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=229) I felt really uneasy listening to this, trying to pick out the sequence. [3:53](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=233) The whole thing is quite unsettling. They treated it like a puzzle, a message hidden in the noise. [4:01](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=241) One composite showed the man with no face. [4:03](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=243) Another showed space imagery: satellites, celestial objects. [4:08](https://www.translate.mom/transcript/dAQxQ9M5hX4a/en/unfavorable-semicircle-the-mystery-youtube-channel-with-72-000-videos?t=248) And buried in the audio was a voice reading coordinates, latitude and longitude, pointing to a spot somewhere in the middle of the Atlantic Ocean.
