Apparently he's using a bot to spam, posting some 10 message per min per minute, each post hits ~14 people, with a link to programing question separate from the post, so that people who reply to the question thread don't see connection with his spam, and just thought a lot people like his questions.
here's a short collection of his spam. This is 2019-01-02.
The name is from my Visual Dictionary of Special Plane Curves project, on the web since 1997.
