I have some tickets to big gigs coming up and they cannot be resold. On Ticketmaster.

Because it's up to the event promoter if they want to enable it

Sure, it’s still the same Ticketmaster.

> allow ticket resale only through the official platform and cap it at the original sale price.

That obviously doesn’t work because money can still change hands outside the official platform, unless you mean resale to a random buyer selected by the platform, in which case the resale is not terribly different from a refund and restock for any event where scalping is a problem.

You simply can’t stop scalping if you allow resale. Heck, people even attempt to scalp things where there’s no official resale mechanism (e.g. I change my id at this second, you immediately change yours).

A lot of festivals in Europe use ticketswap, your ticket gets raffled off to a list of people interested in buying it. It's the only way to sell your ticket. It's a the original price plus a small fee
