My tactic when trying to find this kind of reference is to use a user page search. If you can recall a suitable keyword then it you should be able to find the discussion here. I couldn't find anything based on 'basilisk' or 'censor', unfortunately.
After more work than I would honestly prefer to put into such an effort, I eventually found this post:

As a curiosity, this post cannot be found from my user-page, nor can it be found via Wei Dai's app. Fascinating.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
