URGENT: Social Network Site - User Registration Issue

We have a social networking site where user's status keeps updating on registration to a different 'Status' number - 1 = confirmed email, 2 = profile set-up 3 = deactivated. Noticed that some users are being set as status = 3 before they even get the chance to complete their details in our system. Require a developer to check on this and keep monitor of this for 1 week to ensure issue is not continually presented.
