Your posts stood out (e.g. as rapid, aggressive, and unsubstantive) on a flamewar-prone topic. It's possible that others did worse and we didn't see it; we don't see everything or even close, so that's always the likeliest explanation.

When accounts do that, we sometimes rate-limit them. It's not great but it's one of the few tools we have for protecting HN from the destructive effects of such discussions. If people want not to be rate-limited and are willing to commit to posting civil, substantive comments only in the future, they're welcome to email hn@ycombinator.com.
