Hi @Paul_Holland ,
I am so sorry to hear your losses. Yes, the Cardano Foundation, IOHK team, Emurgo and the Cardano Community already tried their best to inform the scam stuff during the sign up of Daedalus/Yoroi walllet. And also try to take down scam youtube channel as much as they can.
The exchange needs to do that also (Binance, Kraken, Coinbase, etc.)
