Hi!
I'm afraid you've misinterpreted a technical feature as some kind of foul
play.
Trisquel's user forums and mailing lists are synchronized so you can
participate on them both through the website and through you preferred e-mail
client. J.B. Nicholson-Owens is not using any admin privileges, just probably
quoting some lines through the "reply" function of an e-mail client.
Any mailing list works through e-mail addresses, and any mailing list user
can see the e-mail addresses of other subscribers. This is not that obvious
when signing up to a forum and hence not ideal here (this topic has been
brought up before and we intend to improve on it in the future), but it's
actually warned at the "create new account" form under the e-mail field. The
line you show at the screencap is related to the private contact form and has
nothing to do with this situation.
I hope this clarifies your doubts.
