No, just me. Instance-banning is when you ban a person from your instance. It's essentially an individual-level defederation in that you can still take part in their threads, it's just that no action you take will be mirrored onto their instance. Everyone else can still see it though, which is why you can see me absolutely swinging at beehaw's social fascist moderating. (assuming grad hasn't defederated from that neoliberal shithole)
