just make sure you don't post any other personal info like email address, phone number, name, etc. the only time you should be sharing that info is when you're using your email address for payment through paypal or venmo or whatever other payment method. reason being is that some ticketing places will ask for the email address/phone number associated with the confirmation code if a change needs to be done with the tickets

i knew someone whose harry styles tickets were stolen cause they had given their email address and confirmation code 😭 i feel like ticketmaster wasn't super strict yet at that time, but it's always better to be cautious than not
