I know the feeling, believe me, but from a mod perspective I can tell you that everyone always feels that way (myself included). It seems to be a hard-wired bias we all have. Therefore, everyone needs to make a conscious effort to follow the site guidelines despite that feeling (myself included). I appreciate your response!
We rate limit accounts when they post too many low-quality comments too quickly and/or get involved in flamewars. Your account is rate limited because it has done a ton of that.
All is not lost; if you use the site as intended for a while, i.e. posting substantive, thoughtful comments that follow the guidelines (https://news.ycombinator.com/newsguidelines.html), you'd be welcome to email hn@ycombinator.com and we can take a look and hopefully drop the rate limit.
