Coming to think of it, there has been some spam lately (though that hasn't happened in years now at gmail), and I wonder whether it's related to that Adobe leak.
I don't find any of several accounts I use on there, but did find a friend's email listed (and just notified him). I'd actually appreciate a way to query my mailing list in an automated fashion.
The reply address for spam is almost certainly bogus. And I don't think it makes sense to target people who unsubscribe for more spam. They ain't likely to buy anything.
I have a couple of email addresses that thanks to that address either having been sold, hacked or given away by including in the to/cc field of a mass mailing are now out in the public domain, and I get spam (and almost certainly malware attempts) on those two on a pretty regular basis. I'd prefer to not have the rest of my email addresses end up in the same situation.
