PubSub Server Error Response

Yes, but only if you have a oAuth/token from that streamer with the relevant scopes. And kinda weird to be listening in on their whispers.

Not really

but heres my listen send, near enough:

ws.send(JSON.stringify({
    type: 'LISTEN',
    nonce: 'ARandomString',
    data: {
        topics: ['atopic','anothertopic'],
        auth_token: 'atoken'
    }
});

atoken is not preceeded by oauth:
