A picture to understand:

The real danger is not the verification code platform itself, but treating it as a long-term identity

The essence of verification codes is only one thing: one-time validation

Multiple people using the same number, being registered, or flagged is not a platform problem

It's your illusion that "temporary tools can be used safely long-term"

Experts use verification codes for: testing, validation, and then leaving

Beginners use verification codes for: binding, stockpiling numbers, waiting to be banned

Remember this: verification codes can pass validation, but they can't save your account
