Do not use Adult Hub. It is basically a scam.
We signed up as a couple, first unpaid members and of course we couldn't do anything.
OK, so we paid up for a period - to VIP membership. Got many emails from unpaid (nearly all are unpaid), mostly looking like standardized text like "Hey you look really sexy, couldn't miss your profile. Get in touch".
If you reply to these, you never get a reply back. You often get yet another "Hey, I'm interested" after you sent a reply saying "yes, let us meet". Clearly nobody can read your reply even if you paid up.
I tested it by adding several free profiles as well as our paid one. An unpaid member can ONLY email a VIP (all others get just blurred text). And only shortly after signing up. After 4-5 emails to VIPs, things start to blur.
Only chance an unpaid member (99% of everyone) has, is to sign up, then as first few emails - contact VIP members and sneak in a crypitic ref to email. If you exchange more than 1-2 mail with someone, you get blurred and you need to add a new free profile. It works with various disposable email addresses, so go for it but DO NOT PAY THEM ANYTHING. You get precisely ZERO for your money!
