The problem with that home verification is... verification. If you leave it up to the honor system, then you end up with a lot of "fierce" fatties that think the website will be an easy source of thin/fit men that will want to have sex with them because Tumblr says that empowered fatties rock want to defy your objective standards of female beauty and just sign up anyway. If you verify by humans, then eventually you'll need to deal with the potential of a bunch of shameless SJWs spamming new accounts to the point where the workload becomes too much and the verification process is harmed. No verification = no new users = no users
