(Edited your post to remove the domain... Obviously don't want e-mail harvesters to add that to their list of spammable e-mails!!)
Yeah, I don't know, I never really bothered about what e-mails sent to that address would do. It's customary to just ignore them anyway, or bounce them back... I don't know.
As for spam lists, obviously I'll do all it takes not to end up in those.
;)Except it's just so complicated-- if I add an Unsubscribe link to e-mails, they'll be sorted as Promotion items by Gmail, making them less visible (unless you manually move one mail to your main inbox, and then set it up to always do that. But... Who knows their e-mail software well enough?)
I read on a website that you can add that link as a 'signature' to your e-mail, which sounds strange to me. I figured Gmail would immediately see an Unsubscribe link as what it is, rather than say "okay, it's after the -- signature mark, so who cares if it says buy vi@agr@ for $0.01 right now and get a free pen1s enl@arger? It's just a signature..."
Seems to work, but please add a permalink notice on every list so it's more visible.
UPDATE: Added permalinks on all list pages.
UPDATE: Your own profile now shows your lists at the same place as other profiles do. It's mostly so as not to disrupt your experience, I'm not sure that box is necessary, especially after adding permalinks.
FIX: Users who have a Barter account and created it after March 23 should now be able to import their lists from Barter. If you can't see the button in your list pages, log out then log in again, should fix itself.
