As a recent example: If you come into a place to share an opinion, this escalates into an argument you insist on maintaining, and then you pull up to adjacent spaces a day later to continue the argument when people are doing nothing related to the subject, I will absolutely hit you with a command-line ban and go on with my day.
If your response is to make a public, snide remark behind that rather than reflect on why that happened, I'm going to chuckle on the way to my teapot.
