How does the Modlog actually work? - eviltoast

So, I recently came across a post on lemmy.world (my current instance) where every comment showed up as “removed by mod”. I was curious to see what happened, so I opened the Modlog, filtered by “Removing Comments” and cycled through all the mods of that community (not sure if there’s a better way), but found absolutely nothing. Am I using it in the wrong way? I can link to the post if the moderators confirm it doesn’t count as witch-hunting.
