I think you might be referring to the BTS online archive!

Some popular content you can find in the BTS online archive includes:

• Do not archive paid content: Do not publicly share full downloads of paid concerts (Muster, Yet to Come in Busan paid stream) or Weverse paid membership videos. This damages the artist’s revenue.
• Respect member privacy: Archive public broadcasts, but do not preserve or distribute leaked private data (old phone numbers, private family photos, airport security footage).
• Credit translators and subbers: When re-uploading subbed content, keep the original subber’s intro/outro. Removing credits is considered a cardinal sin in archive circles.

The internet was supposed to be forever. That was what Jimin told himself as he sat in the dark of his apartment, the blue light of his monitor washing over his face. But for the past three weeks, the internet felt like a graveyard.
