This sort of unilateral action-before-asking is imo not a great signal to send out if you're trying to grow a platform. If you're going to run experiments, let people know first.
Could I also suggest making the comment text size larger (it's smaller than CSS 'small'), changing the typeface to be proportional, and most importantly making sure the contrast between foreground and background elements is WCAG-compliant? Most of the text is less than 3:1. Currently the site may be quite challenging to access for a visitor with visual impairments, and I think many such users would enjoy a site such as this if it were more accessible. Thanks.
