ANNOUNCEMENT Spice World 2019 Tour - Tickets on sale now

I’m confused why I’m able to see loads of tickets for sale on Ticketmaster when they’ve supposedly sold out? For example I’m looking at Wembley on the 15th.
Oh, I’m seeing them listed as “Platinum Tickets”. Does anyone have any experience with these? It just all seems a bit weird that the show is sold out except for these platinum seats...
Platinum tickets on Ticketmaster: "No these are not resale tickets. Platinum Tickets are being sold for the very first time through Ticketmaster."

If you ask me it's a bit of a con, designed to get people to spend even more money on tickets.
Yeah, I guess they can state this because sellers are “re-selling” them directly through Ticketmaster. Therefore Ticketmaster don’t think they’re “second hand” as they’ve only been handled by Ticketmaster.
