You came late to the party, and only upvoted after I pointed out the downvote. The scores are getting kind of meaningless now anyway - moreso than normal, at least.
But yeah, that’s a funky bug I’m quietly aware of. It works on Jerboa as well, and a few others (but maybe not the ones that are merely web wrappers). Seems like the back end API still gives you access to comments that a user has deleted. There’s apparently 3 levels of deletion - user delete, moderator delete, and purge. I found a comment earlier that was deleted, when I looked inside it said *permanently deleted*
