Im going to say good luck to scammers.  It will get trace.  Keep the BTC address and give it to the exchanges.  It can slow them down.  Its not perfect but this would catch the stupid scammers.

What would help greatly if they give a fake name.

Always pressure them to ID themselves with selfie picture,  written date and QR code (BTC address your sending btc to) next to them.   When join the groups.   It will always stick to them forever.

Dont join if they cant do this.
