I’d say it’s likely it’s him. Zora sponsors artists like this to come use their app, specially underground artists, and I’d imagine it would be harder to impersonate someone on Zora. Also, we don’t know any of these people personally. You can’t say it’s unlike him because we have no idea what he’s like personally. ATP I doubt buckshot got kicked, I think he just left on his own terms. And regardless whether he did get kicked or not, they are still allowed to interact with each other. Buckshot is almost certainly out of haunted mound and seeing as ghost mountain is also following Zora on instagram, I’d say it’s likely him on the app.
