@SmokeDetector This answer and the user's
other answer are copies of the code on the site's pages the user links. Given the page the user links to in this answer was created yesterday, I suspect affiliation, but can't demonstrate it. The site is prominently copyrighted and I see no licensing information. While there is a link in each answer, neither makes clear these are just copies w/ insufficient attribution (or that the user is affiliated, if so). So, plagiarism.
