This is false. Nothing was done to your account at that time, whereas rate-limiting was active on your account at least two weeks ago. Rate limiting is applied to accounts that do things like use HN for political/ideological battle, or post too many low-quality comments, both of which you've been doing. Here are some of the worst of the comments you've been posting in recent months.

The A16Z title issue was no great scandal. It was bog standard moderation, with attention and responsiveness to community sentiment and feedback. That kind of thing happens all the time.

Meanwhile, you post too many comments that break the guidelines and use HN against its intended purpose. HN is only a place people want participate because others make an effort to keep the standards up rather than dragging them down. Please do your part to make HN better not worse if you want to participate here.
