Well, it looks like the thread on moderation was locked? Not sure why and I didn't see any comment related to locking it.
I believe that there might have been a typo on John Joslin's email address. I believe it should read: [personal email addrressed removed] Can the Admins please resend to that email address and see if it arrives without being bounced?

In my opinion, banning users, deleting messages, and locking threads, without letting people know why, serve no useful purpose.
As shown here by a blatant and well know example, a banned user can reappear as many times as s/he sees fit. Unfortunately, the useful contributors that get banned are tending to never come back, which is a shame and a great loss.
Deleted messages without even a simple "message deleted by XXX" notice create confusion with the time stamps and incoherences in the remaining thread, and don't help other users to see with examples the kind of behaviour that can lead to deletion.
And locked threads without an expression of cause are just irritant, not informative.
