APC is a community focused on pilots helping pilots, sometimes it's tough love, but hopefully advice always comes from the intent to pay some goodwill forward. We hope so anyway. We also find that regulars in the regional forums are best prepared and equipped to share current information for those pursuing employment doing part 121 flying.
Sometimes there are new users so completely clueless, angry, and unable to use the search tools, but fortunately those cases are rare. While we don't like to limit access to the pilot forums, sometimes new users earn that restriction. This is a community and as the admin I want to be responsive to the forum users, but I firmly believe giving a leg up to someone without connections or insight is just good karma.
We were all there at one time, relax and pay it forward.
As for the registration email, it doesn't have to be an airline email, just a non-freemail account.
