But right now I have zero knowledge of your reputation. I have zero interest in finding out the reputation of "user norir"... I am evaluating your statements one at a time, without interest in your historical activity.
I would expect the same of readers of my posts... I highly doubt anyone is digging through my old posts. Who has the time? For what purpose?
The exception is maybe a big claim you make. Perhaps a controversial claim which is hard to verify, and people may then look at your past comments. But if you're not making any big bold claims, or leaking juicy gossip, or dropping any unbelievable truth bombs....
I think your account churn is motivated by something else. It's your business, it's all good, but your HN account reputation wouldn't be used against you. Every day is a new day, and people gravitate towards good faith discussion, don't they? Your spicy post from the other day is forgiven! (to be clear, I am not aware of any spicy posts you wrote). Good luck.
