Scammers are an increasing problem for community managers. Most of our moderation efforts (daily) now revolve around security rather than moderating actual discussions, which for a community of over 100,000 members is a nice problem to have, I guess.
However, the biggest issue we see these days is hijacked accounts. Not new accounts.
Their account has been compromised in an external data breach, and of course, because too many people use the same password everywhere, they eventually get into our community after monitoring their victim's email inbox for a while.
The first thing they do once they get access to a user's account is change their email address to one of their own so as to not alert the owner of the account. Sure, the system emails the original email address to let them know that it has been changed, but by then it can be way too late (as we have seen first hand).
Now I understand we can change the settings to require Admin Validation of email addresses, but that applies to New Member Registrations AND existing members. We don't want to have to approve every new member (we'd need a full time staff member just to do that daily). But we want to Admin Approve email CHANGE requests for Existing Members. That functionality doesn't seem to exist presently?
