I'm sorry your account got rate-limited (I'm a mod here) - it's a restriction on new accounts that's based on past abuses by spammers and trolls, and is not intended to prevent authors from discussing their work here. I've marked your account legit so this won't happen again, and I'm going to restore your comment that got throttled.

This is a significant drawback in HN's system and we're intending to fix it.

Calling somebody's work "bullshit" is about on the same level as name-calling, even if your criticism is totally legitimate. In general "it's true" doesn't really make sense as a defense for incendiary words. So I don't think it's unreasonable to say your headline is in some way trolling. Of course, it's hard to blame somebody if the thing they're replying to is dramatic enough, but I just don't think bad journalism on a tax article (giving you the benefit of the doubt - I don't know who's right) meets that bar here. There's enough noise in the journalist-hate genre that it's already a job filtering it down to the reasonable critiques.
