Welcome, and thanks for the suggestions!
This is interesting, though I think we’d want to support this on the badge page itself before building it in to Discobot? i.e., when I look at the badge tell me how close I am to achieving it. This has been requested a few times in the past, and adds to the “gamification” element that badges bring.
Can you describe the problem this is clarifying? Did someone think this meant you only needed one like across 20 different posts? The current text seems clear to me.
