Thanks for the correction! I should probably add an indicator on the site for which bots leave a comment vs which don't (assuming there are any that don't right now) but need to make sure it's not confused with the icon for whether or not the bots allow upvoting comments vs top-level posts.

Also I'm pretty sure there's no legal requirements regarding disclosure of paid promotions, but if you have evidence to the contrary I would be interested to see it!
