A lot of people used to bypass the "Dont let time run out" bans by letting time run down for 2:59 and then resigning with 1 second left on the clock.
This was implemented to stop those people.
I understand it is annoying, I have gotten upset at it/similar before myself (in my case: I had a completely winning position, then my opponent played a complicated move, I thought about how to counter it & forgot about my clock, timing out. Rather upset with myself already, I saw a bit of red when the automated chat system then also issued a warning to me for "letting my clock run out"), but sadly there are sufficiently many toxic idiots on the internet that it is required.
Basically, if you know this isn't actually directed at you (you did nothing wrong), just ignore it. You're not actually gonna get banned unless this happens several times a day, and it shouldn't.
