Maybe it's generational? I meet people in the US and "hey lemme get your insta" just rolls off the tongue. Sometimes it hits, occasionally it doesn't, but it sounds like WeChat is the platform point in China, whereas we have a fragmented array of apps - TikTok/Snapchat/Facebook/Instagram/threads/telegram/signal/whatsapp/iMessage to choose from.

How do scammers work in China/WeChat? Fake Instagram profiles pretending to be someone I know, asking for Bitcoin is a common scam.
