I honestly didn't. I read the first two replies, then posted. I believe a profile link for Jumbo Ticket's Bitcointalk account should still be posted in the OP, just to let everyone know officially that it's the real account.
You didn’t read the OP either or missed somehow mate. Just read the special note put below of the thread. I have linked the official account of Jumbo Ticket there.
I honestly missed it, or I would not have asked. But I saw it later when another poster scolded me to carefully read everything. Hahaha.
Getting back to the issue- Phone Number
I believe Jumbo Ticket should consider this. There are more ways to prevent abuse of the bonus. But most users here don't like to get KYCed.
It's a necessary trade-off in my opinion, or else Black Hats who can hire people from a service like Fiverr can take advantage of the bonus in Jumbo Ticket, by large numbers, like they did with BitLucy. Although users can sign up with Gmail, I believe give another option for other users to sign up without the phone number requirement, but not allowed for ANY bonuses from the site.
