I feel you. I recently commented on a post that was a twitter screenshot, simply asking how that got so many likes when it didn't even make sense and someone attacked my entire post history and that comment got tons of upvotes. Reddit has become a nasty place, not just politically.
not only not working for me, if i try downvoting a comment, it drops to 0. but even then, when i refresh the count is back to what it was before.
