Since you didn't reply to my follow-up post, I'll ask you this:
Can you show me 1 legitimate gambling website that requires a phone number?
I can name you 5 that don't.

It's not his casino/site, he's just trying to get referrals from this thread/site. riobet is not a true bitcoin casino, that's why they ask for IDs. most of the sites like riobet recently adopted bitcoin.
