No, not at all. Don’t do that: Nothing prevents a crook from selling the same ticket many times. Tickets are electronic, they have a single-use QR code.
So, if you come at the gates with such a ticket after it was already presented by someone else and scanned, you’ll be denied the entrance of the festival or compelled to buy another ticket!
If you decide to take your chances anyway, pay attention: “social” tickets are for residents of “social” countries. If you show up at the gates with a “social” ticket and you can’t prove you’re living there, you’ll have a problem.
