After getting muted in multiple different time of the day, it's hard to imagine there's one Codeforces admin actively checking posts all day, so some kind of automatical muting is likely involved and I have no idea about the exact working principle. Please share your experience in the comment section if you have any.

Also I'm fed up of getting muted for saying literally anything in my comments.
