I’m not able to verify the exact Roblox username from the information available here, and the phrase “the Blocks youtuber” is too vague to identify one person confidently. The only solid Roblox-related YouTube result I found was about a Lucky Block event tied to LukeBlox and CoralBlox, but it does not state a username for “Blocks” itself.

What I can say

  • If you mean a specific Roblox YouTuber, the name may be one of the creators connected to Roblox block-themed content, such as LukeBlox or CoralBlox.
  • I did not find a verified source that says “Blocks” is the Roblox user name of a YouTuber by that exact title.

Best next step

Send the exact YouTube channel name, a screenshot, or one more clue, and I can narrow it down fast.
