I honestly don't know. I think I'd let my community decide, which will probably lead to a ban, but I myself don't really know.
Because even if it works like with Jabber or XMPP like many in the comments mentioned the people on Instagram, etc would have the argument that "we could talk to them if we didn't ban them, so why should we switch". But why would they switch if we ban insta. I don't know, but I think it could benefit the fediverse and it could really harm it.
