What would actually help the scammed families would be getting the lost resources back, at least partially. I realize that it may be hard, for the resources may have been squandered. Scamming would be much less prevalent if money were trackable, scam transactions would be possible to roll back, yes, transitively, from all the downstream users. The downstream users would then be keenly interested in the provenance of the money they're being paid. Ironically, blockchain-based currencies are perfectly trackable (at least in theory; mixers make it harder). Sadly, this has a ton of obvious privacy implications.
