I've had two friends that fell to a pig butchering scam, and lost thousands. One was from a dating app (maybe romance scam than pig butchering?), another was via a foreign student in an online class the friend was taking. In both cases, fake / scam crypto sites were involved.

The only way to help with this is education - maybe we need a course on online scams that kids need to take to graduate, along with personal finance.
