@CodyAldaz Looks like it. Right before that they started deleting all the data. Luckily I caught that and rollbacked. When they realized they can't permanently delete their question, I think maybe they decided to leave? It is part of the initial terms of use though, that once you ask a question it can't be deleted if it has an answer with at least 1 upvote. This is why Peter Morgan couldn't delete his "how do quantum computers solve drug discovery?" question even after so many downvotes.
It's a bit unfortunate that Tyberius went through all that effort answering the question (I feel a bit bad because I got him to write that answer)
At least it brought in another user though (the developer of the specific python package that was being questioned).
I think these things will happen from time to time. I see deleted users all the time on the network. I think the user wanted to "use us" to get an answer, but then didn't want his supervisor to see that he asked publicly. When he realized that the "delete" button disappears once there's an answer with upvotes, he tried to delete the question manually, and when he realized he couldn't do that, deleted his account so at least his name wouldn't show.
It happens. We'll get people asking questions that they don't want their boss to see.
