You missed it.that rule is:
THE RULE
The rule is the same as for other sponsorships in the past:
"All posts for any download links on Akiba-Online must contain a FileJoker link. You can post other hosts too, but it must include FileJoker link(s). This includes reposts of dead files."

"What this means is that Akiba-Online expects all Direct Download posters to include FileJoker links in their posts."
You’ve been here long enough to be familiar with the posted rules. FileJoker links are required for all posts in the Direct Download section and sub-sections. Those areas are specifically for uploaders to flatly post links and nothing more. This is the Discussion threads. Read from post #1 in this thread. We talk(ed) about how this form of JAV evolves, gains traction and becomes more popular, how, if, and when the Studios will adopt it, and how to use the various headsets, apps, systems, to enjoy the VR experience. The posts here are for people to try VR titles so they can get them excited about it.
