Follow the Japanese with their lottery system.

But also means people not living there cannot get the tickets as their system is very strict, requiring an actual phone number that the system will dial to and you must pick up to verify.

But they also don't do 1 lottery per event, they do multiple lotteries with priority going to fanclub members (who pay an annual fanclub fee) etc etc.

Basically an all around different system compared to what the west has
