Personal attacks are not ok on HN. New users with expertise or knowledge about a topic are welcome here. If existing users harass them and hound them away, does that benefit this community? No it does not.
This comment was so far beyond the pale (plus you posted so many unsubstantive comments elsewhere today) that we've banned this account. If you don't want to be banned, we'll happily reinstate you; just email hn@ycombinator.com and give us reason to believe that you'll follow the rules in the future.
