It is a feature, but it's hidden, so you couldn't have seen it. I think you need to add ?exclude=tg.horror to the URL when browsing.
Aha! That's great to know, thanks!! I'd love this to be more widely known if not added to the UI, even if it was in an "Advanced search techniques" popup or something.
Is there a way to exclude multiple tags? I tried a couple of things but couldn't figure it out, if it's possible at all.
If there is, I'm not aware of it.
