Need★★★☆☆Feature request

大约一年前左右，Facebook Messenger 开始要求我输入一个6位数的 PIN 码，这样"Messages in Messenger 可以被恢复"。我忘记了这个号码，看到我的消息被删除了一年左右。此外，当我交换消息时，我看到我无法发布，随后消息被删除到2024年9月... 有人入侵了我的账户还是这是某种"合法的"Facebook Messenger 功能？ Chinese research excerpt

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Evidence-backed” means the problem appears real, recurring and connected to spending. It does not mean the business is worth building. Read the full methodology.
