It's because you're new. Powerusers can downvote and even flag comments. A couple flags and the comment is (by default) invisible. Enough flagged comments and your comments are flagged by default. There's a reason this place is called orange reddit

I created this account in November 2009 and am fully aware of what "power users" can and can not do ;)

Sorry, but 50 day old accounts shouldn't so confidently (yet incorrectly) explain HN to other users. This is not really how it works.
