Ask HN: Why does account age matter?

When a person posts from a single purpose account or a sock puppet for the precise reason of obscuring their anonymity, why does some user always attack them for having a new account as if they the person was also created recently?

Are these bots whose LLMs actually think they are talking with a person that is 13 minutes old or whatever?

My main question is: What does the age of the account have to do with the point being made? A good point is a good point. A good question is a good question.

What’s even crazier is nobody cares if the account is anonymous as long as it’s old.

Never understood that one, and I see so many conversations derailed by it that I wonder if it should be a rule: Like ad hominem attacks, any sort of argument involving the age of the account is a logical fallacy.
