Good Day Everyone!
It's me again, @Great_Influence .
When someone marked your comment as spam and he/she said it was unintentional/accidental and it was already UNDO still the damaged has been done. Even if it is already UNDO you will still received low points throughout the day.
In my experience, you will be muted when your comments was marked as spam 3 Times. In my case it was with three different users. Or maybe you can still be muted when a single user marked your comments as spam three times.
This is my opinion based on my experience.
