Suggestion for "moderation"

[Jonas Lund]

I've had enough of spam and crackpot-newsletters now. And i'm on the
verge of unsubscribing as i guess instituting full moderation wouldn't
be very practical (i'm sure most people don't get paid for sitting
here)

Altho just leaving and complaining won't help anybody (and i do love freebsd).

So....
Isn't there some kind of auto-moderation system that could be placed
in (Plugin or whatever)? Like delaying the mails for an hour for all
newly subscribed users (so kicking people off the list will force them
to re-list) and then just sending the mail in advance to "moderators"
that would have simple link that would remove the mail from the queue.
(Maybe one hit on the link would delay the mail futher and several
clicks within the timespan would kill it).

This way message will get through by default but annoying stuff
wouldn't affect everybody.

Just another 2C
