temporary ban

in this match

I was winning I'm a bit slow I lost I do not understand this message here
"Warning, datteriant Letting time run out instead of resigning will result in a temporary ban"
.

@datteriant

It's not a big deal, don't worry, the lichess algorithm just noticed you ran out of time in a middlegame. Some people, in a losing position, will waste time just to be a nuisance. Nice game though. Don't worry much, but you might want to pick the speed up a bit more; to prevent this message from even occurring- it's a warning, but isn't necessarily correct.

When I ran out of time, the system gave me a different kind of warning, saying that losing on purpose would end in a ban. I wasn't losing on purpose. It had been a very short time control and I simply ran out of time. How does the system think I was trying to lose on purpose?
