Xiaohongshu has become much more sensitive to changes lately. Normally, it's fine to use the platform without real-name registration; there's no mandatory requirement. But in my case, I was forced to register because I switched IP addresses. One identity can only be linked to one account, and unlinking after registration is troublesome. In situations like this where you're suddenly forced to register, consider whether the account is worthwhile. If it's not valuable, it's better to just create a new account and start over.
