Justin Y.

Justin E. Young, known by his online alias "Justin Y." and formerly "Jeyoung624" and "Justin Young", is a YouTube user who is known for frequently commenting on other people's videos.

About
He is known for frequently commenting on other people's videos, making him "being everywhere" in the comments section of many videos of many creators (especially to the ones he subscribed to). He usually comments memes and jokes (specifically on videos related to memes), and comments on videos talking about him.

There are many theories of him using likebots, but in fact, he never did likebotting. It was in fact, all a coincidence that most of his comments appear on the top comments. Also, his comments aren't always on the top. In fact, he sometimes adds comments that only get 60 likes. He confirmed all of this on one of his posts on his subreddit.

Trivia

 * His location, which is Antarctica, is obviously a joke.
 * He only uses Discord, YouTube and Reddit.
 * He is the first YouTuber to surpass 100,000 subscribers without videos, so it would be possible for him to make his first video being him unboxing the silver play button.
