You should start a forum, and all that wont's to join must must register there (Then you have a community from the start). It must be a forum where we can give ratings to the users. Then you have a post on bitcointalk, where all the users can verify their account. Then encourage all to check users, and give negative ratings to users who may be cheating. Users must have at least a given number of posts, and the must be serious post and not just a begging accounts. Then the community will, help you verify valid users


Edit:
Still got nothing
