However, all emails sent to these kinds of addresses are returning back to us. This was already happening, but it was not bothering us so far 😄 unfortunately, recently we started to have a lot of "Delivery Status Notification (Failure)" emails... so, we would like to solve this.
Address not found
Your message wasn't delivered to [email protected] because the domain facebook.com couldn't be found. Check for typos or unnecessary spaces and try again.
And on the Facebook postmaster page, we can confirm the problem as "RCP-P1 The attempted recipient address does not exist."
Since the forum sees these accounts as valid and activated, it keeps trying to send an email at any action that causes email delivery. And of course, all emails are being failed to be delivered and returned back to us.
Removing view privileges from spiders will get rid of most, but not all crawlers. As @gotwf says, crawlers are not the most law-abiding scripts out there.
Simply removing all guest privileges should do the trick, but if you're regularly copying prod to your dev forum, then the more surefire way to keep EVERYONE away would be to restrict access to a single IP or range (e.g. a VPN) you control.

Are these warnings meant to interest me or can they be ignored?
@crazycells I could do that, but I would hate to force him to reset his password. If there are no other ways, I'll just revoke all users sessions. Or, I guess I could catch him online one of these days to revoke his session.
