Jutobu is the user? I have reported a few seconds ago the same issue in Spanish, a lot of users with the same problem
Weird/Significant Glitch?

Same issue here, the problem occurs when I try to start a game online. Playing against computer and when navigating Social it works normally

No, it seems that everyone who has responded to this post experienced this, but logged in as different users. Very strange.

Yes, it's the same for me. I only appear logged as him in the main page, and when I go to statistics and other sections my account comes back. But every time I go to the main page, I'm logged again as jutobu.

When i want to play, rubin guy, when home pscreen, amberlynnrose !?
Those are the accounts I've also had. Strange and concerning.

Me too, I'm a different account on a main page.
That's why you never push code to production without it going through test server first.
When I loaded Chess.com, I was seemingly logged in as another user. This only lasted for maybe a minute, but I stayed logged in as this other user while being able to navigate the website.
The only account that has ever logged in from this computer is my own, so I'm struggling to figure out an explanation other than a significant glitch. Chess.com might want to investigate this issue.
