Usage Notes

Maintain the same network environment. For subsequent logins, always use a node from Japan or the corresponding region, frequently switching between regions is the most common reason for triggering risk control.
Relax within the first 24 hours after logging in. Do not immediately add friends in bulk, join groups, or send mass messages, such behaviors are most likely to be deemed abnormal.
Postpone modifying account information. It is recommended to wait a few days before changing profile picture, nickname, or binding phone number.
