So I was viewing someone's progress chart , and this happened

Now as far as I know , Codeforces is only 10 years old , but it showed the user's latest rating on year 1970
Is this a use case or something like that

Same has happened with me too. Plz. could anyone look into this.
Well, in most programming languages, there is a timestamp (I'm not sure what it's exactly called) that dates to January 1, 1970. There could be a glitch in the system that caused this. Let me know what you think.
I suppose that this is my graph right? The bug temporarily affected me. But it is fixed now as ratings rolled back temporarily.
We can see ratism on it. Just a bug report and downvotes. If the master wrote it, it would get upvotes.
my comment too :(
