Have you thought about providing information for contacting moderators about categories for things you trust them handling without your involvement?
For example, have an auto response PM that basically does this:
Scam alerts: Maged, BadBear
Illegal posts: BadBear
Problems with a non-Global moderator: Maged
I guess what I'm saying is that with that many PMs it's probably worth your time to start going through and categorizing what the top reasons are that people PM you and using an auto-responder mod (like
this) to let them know that if you don't respond within 24 hours they may want to consider contacting X, Y, or Z.
On a somewhat-unrelated side note, has anyone else ever had problems with reCAPTCHA? When I was trying to get theymos's email last week I failed on it 8 times in a row before I gave up and got it from pgp.net.
Here just now the two words were easy for me, but I've had some seriously difficult ones show up on there.
