Quoting Michael Paoli (Michael.Paoli@cal.berkeley.edu):
Other than those atypical settings themselves, I've found no reason for them to be there. In my checking, here's what I found - and what just wasn't there to be found:
You know, I'm going to err on the side of amnesty and remove the sanctions against Michael D.'s posting address on balug-talk and balug-admin. If we-all can't even remember why that was done, I'd rather err on the side of permissiveness.
Searching 'da Interwebs - with demangling of said last name and balug - some search hit results, but nothing seeming of particular relevance.
Yeah, I did that, too. If he'd been a particularly egregious pill in public during living memory, one would expect that to leave a searchable trace.
The awkward bit is that unless I/we have a conversation with Rick D. on the order of 'Hey, guy, looks like some past BALUG listadmin put you under heavy supervision for reasons unknown to us, and we've just removed those', he may keep thinking his Yahoo Mail account is on moderated status in balug-talk and balug-admin[1] -- if he's even aware of that having been previously the case.
(For all I know, he might have walked away from Yahoo Mail years ago. Many people have.)
[1] Whoever put his Yahoo Mail address, within the balug-admin WebUI screens, into _both_ the 'List of addresses which are banned from membership in this mailing list' roster and the 'List of non-member addresses whose postings will be immediately held for moderation' roster wasn't thinking clearly. The second had no effect because of the first being present.
