This is a lot like spray painting a message on a public wall in a neighborhood and then complaining because the community won't paint over it (or destroy photos they took of it) when you realize how dumb it was.
You're writing on a public space for free with no business behind it. You're not the customer in this scenario.
From their history, maybe their comment is this one they wanted deleted:
“software engineer” is such a stupid, shallow and arrogant description. I’m not an engineer and neither are you. I’m a software developer, developer for short. All these fake “engineers” and “scientists” tend to be arrogant stuck up pricks.
Idk OP, maybe step one is to be less of a jerk to people. If you do that you won't have to worry as much about if things are deleted
