Why can't I downvote some comments on Hacker News?

Hacker News restricts downvoting based on user karma thresholds and algorithmic anti-abuse measures rather than allowing it universally across all threads. This lack of transparency causes users to encounter random limitations where some comments show the downvote button and others do not, fueling suspicions of platform interference.
