Ah but he doesn't say that there is no-one with read-only access to his account. Makes sense or else nothing could be done if he had a sick day.

You can give someone the password to your account and have them read your PM's in your absense. If you can trust that person there's no need for a technical measure.
What's the point of reading pm's + emails if you can't act.
He says very clearly he "contacts shareholders himself". So any email you get from friedcat saying shares have been transferred has come from friedcat himself.
You can't get any clearer. He does it himself.
