Go to the "Reports and Studies" tab. It should be the bottom one, mentioning my character's "missing files".
First off, I strongly question the use of blackbox in the Tale. For SCP articles, blackboxes imply censorship. But here… blackboxes seem unnecessary and you mind as well conjure a random name instead.
And another thing regarding your summary here…
Would probably belong in lolFoundation.
You do know that lolFoundation constitutes a specific canon (with specific storyline) and not just a byword for anything involving a goofy Foundation, yes?
As for your story, the idea of the in-universe Foundation interacting with the Foundation site is hardly a novelty. This feels like a cheap reference to the deletion process, when better versions already exist (Funfiction is one example). Beyond those references, there is pretty much nothing to it. As for other cases, they bother to pull off an engaging story (to some effect) before putting in the reference.
Furthermore, the transition from the deletion vote to sandbox is tacked on and unfocused. You may be better off to focus on either, but doing both deteriorates both concepts badly.
