> You cannot downvote comments which are direct replies to your own
Update: my apologies, seems that I'm wrong. The quoted statement is correct. I'm sure I saw a downvote arrow there once, though (but that was in 2017, haha)
Old comment: Maybe I'm mistaken, but I think one can - they just need to click "N minutes ago" permalink to see the down arrow. Maybe it doesn't affect the score or just cosmetic, but IIRC it's recorded and persists. Unless this was changed recently - can't check (but I swear I saw it there!)
