The Great Soyset
From Soyjak Wiki, The Free Soycyclopedia
The Great Soyset was a catastrophic event that occurred on 4chan's /qa/ board on 2021-11-03. During the event, the board was wiped clean of every non-meta thread, leaving 13 threads including the board sticky. This effectively removed most of the soyjaks posted on the board. Furthermore, it became impossible to post due to ongoing maintenance.
In the early stages, it was hypothesised that the The Great Soyset was carried out in response to a recent raid perpetrated against the /lgbt/ board.[1]
It's currently unknown whether the event is related to Operation Clean Stable.
