They added few good security functionalities to their system. Though significant spam accounts are there but i feel at least 30-40% are original accounts. WCEX twitter has around 8k followers.

They added below security functionalities.
1. Recaptcha
2. Email needs to be verified.
3. you can create only one account per IP
4. if you create multiple accounts with same domain they are blocking.


Please add fb authentication also so that you can reduce some more spam accounts.
Please release referral soon, i am eagerly waiting for that.
