Twitter Spam, from “JavaScript teacher”

There is this guy “JavaScript Teacher” @js_tut (aka Greg Sidelnikov), who kept spaming us. This is the 7th time he spamed me. I replied 2 times before, asking him to stop, but apparently he doesn't see it or ignored it.

two years ago, he's struggling, no follower, and i saw him bitching about his marketing skills. Now, seems he has found marketing jackpot, by shady tactics. He now has 20k followers.

Apparently he's using a bot to spam, posting some 10 message per minute, each post sent to about 14 people, with a link to programing question separate from the post, so that people who reply to the question won't see connection with his spam, and just thought a lot people like his questions.

Here's a short collection of his spam, collected from his twitter posts https://twitter.com/js_tut/with_replies This is 2019-01-02.

Greg Sidelnikov sells many JavaScript books and CSS book on amazon. But as far as JavaScript goes, he doesn't really understand it. Lots complaints on amazon of his cash-grab books, and apparently many fake reviews.

His CSS book, titled Visual Dictionary of CSS , the title is copied from my CSS tutorial, at Visual CSS, which was named Visual Dictionary of CSS for a while. The name is from my Visual Dictionary of Special Plane Curves project, on the web since 1997.

Apparently, he got complaints from others.
