24 pixels. Thats the minimum affordance suggestion by W3c (and it probably should be 32px IMO) for a click target on mobile if you don’t want to be the asshole. You make the padding clickable if the target is smaller than that.
> Undersized targets (those less than 24 by 24 CSS pixels) are positioned so that if a 24 CSS pixel diameter circle is centered on the bounding box of each, the circles do not intersect another target or the circle for another undersized target;
I am also never sure if I downvoted by accident or if downvotes are a thing here at all. Sometimes I see up and down arrows, but they are dangerously close on mobile and no matter where I touch they feel like one button anyway. I also could not find a way to see my downvotes, so I am not sure if downvoting is even possible.
EDIT: The up/down arrows work. If I touch the lower half the arrows disappear both and the comment does not appear in my upvoted list. I do get the option to "undown" however (as opposed to the usual "unvote").
My attempts hacking the upvoted comment list URL to find a downvoted list were not successful.
Sorry to parent comment, you were my guinea pig. I restored the upvote, hope the temporary downvote does not hurt.
Some dupe posts I flagged are missing last time I looked at it. Possibly working as intended. Comments from another section are missing from my account that I had wanted to save criticizing the moderating down-weight system too.
