Linus Gabriel Sebastian is best known for his technology YouTube channel, Linus Tech Tips, which has over 12 million subscribers.

Linus is also a huge meme in the Repl.it Discord and gifs of him are frequently sent by Spotandjake, causing AllAwesome497 to give him the no img role.

Not to be confused with Linus Torvalds (founder of Linux). They are probably not the same person, but the shared first name is certainly very suspicious.
