No, Delfy shares glitches and exploits for everyone to abuse in the game, in exchange for viewer/subscriber money. The people who actually find, pinpoint, and report on bugs/exploits are all these people with Finder's Fee hats: https://wiki.teamfortress.com/wiki/List_of_Finder%27s_Fee_owners Even before the Finder's Fee was added, there is still a ton of people with community quality weapons, who received them for finding and reporting these exploits. Delfy simply picks up on their reports, tests the exploit himself, and then shows it to the entire community to create Youtube revenue and an in-game spam of exploits.

Delfy is just an average click-baiting Russian youtuber, who uses a more unique medium (exploits in Team Fortress 2) to secure himself a steady profit. Nevertheless up-voted.
