We rate limit accounts when they post too many low-quality comments too quickly and/or get involved in flamewars, as your account did recently: https://news.ycombinator.com/item?id=33578462. Rate limits apply to all posting (i.e. both submissions and comments).
We're happy to remove the rate limit when we believe that an account is going to use HN as intended in the future. However, you just broke the site guidelines badly a few minutes ago: https://news.ycombinator.com/item?id=33686024. Posting like that will get you banned here! — regardless of how wrong someone else is or you feel they are — so please review https://news.ycombinator.com/newsguidelines.html and make sure not to post like that in the future.
Once you've built up a track record of not breaking the site guidelines, you'd be welcome to email hn@ycombinator.com and we'll take a look and hopefully remove the rate limit.
