Earlier today I hit the 40-vote mark after going on a voting spree (I'd already gotten Vox Populi once). But I noticed that I could still vote on comments.
How to reproduce:
- Vote the max 40 times in a day, getting Vox Populi if you haven't (there will be an indicator saying "Daily vote limit reached; vote again in x hours.")
- Try to upvote a comment. You will see that you can successfully boost the comment's score.
