The whole purpose of the great darkness was a test and an experiment to see what would happen when containment was breached. They faked an 'ack, set up the sharty (which has gone through 3 or 4 owners at this point and is fully nigged) and spammed this board with twitter screencaps for YEARS on end with bots to herd the userbase to the sharty and to the shitter. But the result they got was not what they were expecting at all; instead of the userbase predictably moving from one containment board to a worse containment board (sharty checks for open ports on each page load, it also runs obfuscated code through integrity that bootstraps to intregity.wasm that can hijack your browser among many other horrible security vulnerabilities ((pic related)) and of course everyone knows how much of a shitter twitter is) instead of moving to those boards and sites the userbase of Anon Babble went everywhere and anywhere including outside. This was a wide scale containment breach that anons have always "promised" but glowniggers never thought possible.
That is why the site came back up so abruptly, it was because the glowniggers had lost control. Despite being completely unable to control the narrative on this board or any other board it was still the least worst option they had at their disposal.
TL;DR: glowniggers fucked up!
