Once extremists fixate on a target they do not stop. I've watched it be done to others. I've had to ban people across multiple subreddits because they go to scream anywhere they can and then into my inbox on multiple accounts. It's not good faith behavior. Simply blocking after the fact does not stop it. They find other ways once they have a mission. It's easier and healthier to stop it before it's an issue. It's not so easy as it sounds. It'll persist for as long as they are fixated which is not sane or rational. If it's let in, it changes the culture of the instance inherently.
