<p>I came upon this question which I thought was an interesting probability question and a detailed answer so I upvoted both.</p>

<p><a href="https://stats.stackexchange.com/questions/326346/what-are-the-mean-and-variance-of-a-0-censored-multivariate-normal">What are the mean and variance of a 0-censored multivariate normal?</a></p>

<p>Then I was puzzled noting it was asked and answered by the same person literally within a minute. In fact, given the amount of code and algebra in the answer, I wager the answer was written before the question.</p>

<p>I don't know if it's just for reputation or influencing the content of the site; but is it technically a violation of site etiquette to post personal work, albeit interesting, this way?</p>
