Logged in to geektimes without authorization. Bug?

Question

Habr

I registered on Habrahabr a long time ago, even before the separation, I don’t remember the exact date. My account is the most ordinary, I can’t even comment. Also, since then, I have almost never logged in to Habré and geeks, because I simply didn’t need to.
Now I'm sitting at work, reading geektimes (I have never logged in to TM sites, sitting at work, I always read as a guest), but suddenly I found the opportunity to leave comments.
Checked my account. That is, I magically logged in.
I can’t comment on Habré, I didn’t check the megamind.
Would you like to understand what happened?
UPD:
Found out that Read-Only users can now comment. However, the issue of sudden authorization remains.
