It's completely unacceptable to attack a fellow HN user like this, repeatedly over an extended period of time. It creates a feeling of stalking and persistent harassment, and we cannot let that kind of behaviour continue without consequence. We'll have to ban the account if it happens again. You've made plenty of positive contributions to HN, so we don't want to ban you, but this pattern of behaviour has to stop immediately and permanently.

This account has engaged in a pattern of harassment against me, but its harassing comments get deleted before moderators can notice, apparently.
