Edit: off-topic UI question—my comment was a reply to a comment that its author subsequently deleted. Is that unclear to the reader?
I've noticed that replies to comments marked [flagged] or [deleted] seem to get downvoted more, and am wondering if that's because it isn't obvious that there was a parent comment and it's no longer there.
Edit 2: Thanks for all the replies. It's clearly a problem and I've put it on our list to fix.
