I think they are using some old list, or keep around positives even after they get removed from elsewhere. I'm the OP and nuxx.net was getting flagged by Yandex because I had an old perl script, I believe udpscanner.pl, in a directory as I referenced it in some old writeup. It was actually named udpscannerl.pl.txt, was served up as text/plain, on a server with no perl CGI, and was something that needed to be run interactively from an interpreter. Literally, sample code. Yet for some reason Yandex flagged it as a malicious site. And Malwarebytes picked that up... And apparently continues to do so years after I removed the file and got Yandex to rescan and mark the site as clean.
