What does "This user has performed too many passenger bc operations" mean?

There are two links where this problem will arise: 1. When you choose "SMS" to apply for a boarding pass. At this time, the network speed often lags, causing you to mistakenly think that the text message has not been sent and you ask to send a text message again. As long as you do this more than 2 times (excluding the second time), your online check-in and boarding pass will fail. , and the questions and information prompts you asked appear; 2. When you received the text message and opened it, you saw the QR code of the small number. Although you were excited, you forgot to save it. So, no matter what the situation is, no matter 1. or 2., you must arrive at the airport and re-print your registration card at the airport's re-check-in machine. New stuff is fun, but you can only play it once, otherwise you'll have to replay it at the airport! So, new things are fun, don’t worry if something goes wrong, you can get a replacement when you get to the airport.
