I'm not super active on kbin, but I've never seen anything from Pug to suggest they're a bad person. On the contrary, they're probably one of my favorite posters on here, at least in terms of the content they bring. I also respect anyone here who actually posts content and engages in conversations. It's more than most (myself included!) can say.
Actually, our downvotes don't federate out, and we don't get incoming downvotes either, so you could totally make them private within an instance since that information doesn't leave the instance anyway.

I mean, yeah, you could put "block magazine" under the "more" options. I don't think it would take up that much more space, and you wouldn't even see it unless you clicked "more"
