I received the "Subscription Confirmation" email as well (identical to the one pasted above).
I agree with the others in this thread: not sending out an email to affected people (or barring that, all subscribers) is near-Equifax levels of irresponsible. Very few people will think to check the Photo.net homepage and fewer still may notice the black bar with 0.5em font.
If you're savvy enough to be commenting on this thread, you probably already realize that a safe assumption is that Photo.net was breached and your account information was compromised. While they continue their investigation, it's probably smart to change your password (and passwords on accounts that share the same password -- not that anyone would do this, of course!). Given the lack of expedient and forthright communication from Photo.net today, I wouldn't wait...
